Why is a trimmer for grass began to spend more gasoline. Several recommendations for choosing…

Fuel consumption for a trimmer for gasoline grass for accounting is an example of calculation

Lawn mower. A very simple device. There is nothing special about this. And so many people buy it for their needs, because everyone can learn to work with him and quite quickly.

Anyone who relied on a gas trimmer for grass should know that for him one of the most important characteristics is fuel consumption. And there is a simple explanation for this. First of all, the device must perform its functions for a long time, so that there is no need to refuel for a long time. It is always convenient.

MAIN! However, in this case, of course, the fuel tank will be large. As a result, in general, its design becomes difficult. And this will complicate the work. Is it possible to find a reasonable solution in this situation? You can solve the problem by reducing fuel consumption.

Next, we will talk about how it can be, what the fuel consumption of the trimmer for the grass depends on, and advise which gasoline is best suited for your work.

What to look for when choosing

Gasoline consumption standards on trimmers

For example, Husqvarna 122c, which has a 0.8-liter two-stroke engine, consumes 630 g / kW / h. The fuel consumption of gas mowers STIHL FS 50 CE is 20 percent lower. In addition, he throws 70 percent less harmful emissions into the environment than models with a two.stroke engine.

The following are the tips that experts give users. They relate to the choice and use of the fuel mixture.

Experts advise buying mainly AI-92 gasoline for trimmers. To prepare a mixture with the correct ratio of oil and gasoline, it is necessary to maintain balance 1:30. Violation of this ratio leads to damage to the engine.

Store the mixture in containers that should be clean and safe. Since the fuel mixture sometimes settles, be sure to shake the spray can before refueling.

It makes no sense to pour more gas than you can spend. Then it is better to fill it than to clean the container.

MAIN! The lawn mower will last a long time and will save fuel economically for those who strictly comply with simple storage rules for the trimmer for grass.

The gasoline engine has a complex structure and therefore requires constant care. Therefore, before starting work, it is necessary to familiarize yourself with the rules of operation of the device and follow the recommendations developed by the manufacturer.

It is necessary to constantly monitor the purity of the inner surface of the body. In order to prevent corrosion of caustic grave juice in any part of the device, experts recommend cleaning the machine after the end of work.

Before buying a mower, it is necessary to determine where it will be stored. In this case, it is necessary to consider what sizes the device has. It makes sense to look at the model that folds the pen. In this case, he will find a place in any storage. That is, this option is simply great for storing the device.

Review of the lineup of the Stihl Boisters

The popularity of products from this manufacturer is determined by the ratio of price, quality and reliability. The most purchased models of STIHL gasoline bushes include the following:

• STIHL FS 45 gasoline bureau is a multifunctional model of a professional series. It is equipped with Elastostart for quick starting. A powerful engine makes 9,000 rpm, which is completely not felt due to the presence of a damper that extinguishes vibration. Buyers managed to evaluate the convenience of the T-shaped handle and the bar regulator. In the standard equipment that includes a saw disk, you can additionally add other accessories.

How the oil consumption in the engine is calculated

To determine the norm, the calculation is not the value of the run, but the consumption of the fuel resource. This indicator is more accurate than the distance traveled, because when you stand in traffic jams, the oil is even more depleted, and the odometer does not change its value.

The oil consumption in the engine is customary to count on its volume spent on burning 100 liters of fuel.

To find out the rate of oil consumption in the engine of your car, you need to use the calculated formula and calculator or use this online form. It involves the calculation of the permissible amount of oil to the fumes according to the type of engine, the volume of working oil and the amount of fuel consumed, taking into account the condition of the piston group.

Oil consumption formula

The calculation of the oil consumption can be carried out in the fumes, for the cycle of its work between this and the consumption per 100 liters of the burned fuel. Formulas for these two calculation options will differ. The carbon fumes from the replacement to the replacement are considered according to the formula: QY = ∑Q (QZ-QSL), where ∑Q is the amount of added oil, QZ-oil that was filled into the engine when replacing it, QL-the amount of oil that merged.

To calculate the consumption of flooded oil, which it was necessary to add only for a period of 100 liters of the fuel drunk with a car, the calculation formula has the form: mz = v / (PK), where V is the capacity of the entire engine lubrication system, p is the spent fuel, k is the wear of the piston wear coefficient (differs depending on the engine, if diesel, it is used. 1.25; gasoline. 1.15; turbo. 1.3).

Calculation of oil consumption per 100 liters of fuel

To perform the calculation of oil consumption per 100 liters. Fuel needs the full volume of the engine of the engine (indicated in the technical documentation of the car) to divide into the product of the spent fuel and the wear coefficient. So, for example, if 4.7 liters of oil must be poured into the engine, then at 100 liters of fuel consumed by the engine, 30 grams of oil consumption are allowed. Thus, you can calculate the consumption of engine oil and your car using the formula.

Consumable oil consumption formulas

The total actual oil consumption for the fumes for the cycle of its work (from replacement to replacement) can be calculated by the formula:

Where ∑q is oil, added during the cycle (between then); QZ. flooded during refueling; QSL. merged when replacing.

But the consumption of flooded oil in liters per 100 liters of fuel is determined as follows:

Where V is the capacity of the engine lubrication system; P. consumed fuel k is the coefficient taking into account the wear of the piston group (k. for diesel car 1.25; gasoline 1.15; turbo 1.3).

How to fill in the finished fuel on a two.stroke motor

Many do not comply with some important recommendations for pouring fuel in the gas tank of the trimmer for grass or lawn mowing, which ultimately leads to unpleasant consequences. Consider important recommendations on how to properly fill in the gas tank of motorcycles diluted fuel from gasoline and oil:

Prepare a funnel or watering can. Despite the large diameter of the hole of the gas tank, very often when trying to get into it, a certain part of the fuel is spilled, which enters the tool case

The fuel that came to the tool can cause ignition when heated, so it is very important to use a funnel or a watering can before twisting the cork, you should carefully clean the surface of the tank, since pollution can get inside, which will cause a quick clogging of the fuel tanker should be carried out in the calm The weather or in a secluded place to exclude the likelihood of dust and small grains of sand inside the tank do not leave the open hatch of the tank for a long time, since not only small grains of sand and dust can fall into it, but also insects do not inhale gasoline vapors during filling, Since they are dangerous for humans. When working with a trimmer, the master should use protective glasses, headphones and a respirator to pour fuel into the tank, you need to mark before the mark

If you pour a full tank, then with screwing the cork, some will result in a non.excessive use of fuel. In this case, it is better to shorten than to pour

Given these recommendations, you can significantly extend the service life of the gasoline tool in question.

It is interesting!Work on the preparation of the mixture and pouring fuel is also recommended in protective gloves.

Common malfunctions of carburetors

Damage of the carburetor of the trimmer for grass occurs due to the use of poor quality gasoline, damaged air filter and the accumulation of dirt in the chamber of this block. Most often, it is quite possible to repair a carburetor with your own hands. Below listed typical malfunctions of the carburetor motorcosa.

Problems of the fuel pump

A common malfunction that “pursues” the fuel pump is a deformation of the pump membrane. For this reason, it does not fit properly, and the pumping canals are not compacted.

The reasons for the deformation of the membrane can be as follows:

As a result, damage to the membrane reduces the productivity of the pump, and, as a result:

• the flammable mixture is impoverished;
• The engine is difficult to launch;
• interruptions in the work of the motor appear;
• The piston is damaged.

Also, the above consequences for the engine can cause clogging of the pump cavity from the pulse side. In this case, dirt enters the membrane through the pulse channel.

To eliminate clogging, you will have to disassemble the carburetor and clean the membrane.

Clogging of the mesh filter

A mesh filter can be contaminated when contaminated fuel is received through a fuel hose or a suction head that has defects. In the photo below you can see how a clean filter and contaminated (parts are separated by a feature).

To eliminate the malfunction, thorough cleaning and flushing of the mesh filter will be required. It is also recommended to blow with compressed air all holes in the body of the carburetor trimmer for grass.

The adjusting lever is faulty

This breakdown appears when the contact surface of the lever wears out.

Washing the contact surface occurs due to the presence of abrasive particles in gasoline or due to strong vibration of the motor during operation. This defect in the adjusting lever causes problems with the inlet, as well as incorrect operation of the motor at idle.

Wear of the intake needle

The inlet needle fails, as a rule, due to the presence of abrasive particles in the fuel fluid.

• The insurance of the saddle of the intake needle is violated;
• the leakage of the combustible mixture appears;
• malfunctions in the operation of the engine associated with re.enrichment of the fuel mixture appear.

Also, the intake needle can simply jam.

Singing an intake needle can cause the presence of dirt in a combustible, or a long simple apparatus without work.

Clogging of the adjusting cavity

If dirt accumulates in the adjusting cavity, then the inlet needle cannot lock the hole tightly and a lot of fuel pours into the chamber.

This causes fuel rewriting, and the engine begins to work incorrectly. It is necessary to disassemble the carburetor and clean the cavity of the adjusting membrane.

Deformation of the adjusting membrane

The membrane may be deformed with prolonged operation of the unit and when using aggressive fuel.

The impossibility of normal adjustment due to the defect leads to:

The problem with the intake adjustment lever

This problem may occur if the adjusting lever is incorrectly, or bend it before installation. As a result, the contact surface takes the wrong position, which violates the additional fuel supply.

Damage to the damper

Throttle and air shutters basically wear out due to the presence of abrasive particles in the air. Defective shutters look as if they were subjected to sandblasting.

As a result of wear of the damper, the engine performance decreases, malfunctions appear in its operation, piston rings, piston and cylinder coating wear out.

Wear of the throttle and air damn

The shaft of air and throttle can wear out for the following reasons:

• insufficient and incorrect air filter maintenance;
• The air filter is damaged;
• The air filter is unsuitable for this device.

Due to the ingress of poorly purified air, the shaft wears out and may break. The broken parts of the shaft can fall into the combustion chamber or the engine of the engine and cause serious damage to the entire piston system.

To eliminate problems with air purification, it is necessary to replace a defective filter or rinse the existing (working). The filter must be washed in soapy water and dried.

Signs of unbalancing

Carburetor debugging is necessarily carried out in the manufacture of the device. As a rule, the owners will learn about the need to adjust the fuel supply with their own hands only after quite serious breakdowns, in the process of correcting which, the module was removed and, for example, cleaned.

Signs of failure in the settings are the following:

• starts up, but immediately stalls the engine. since the engine can only work when a certain amount of gasoline is supplied, with too “poor” fuel, that is, overlapping the supply channel, the motor will stop;
• too much fuel consumption, many exhaust gases. the result of incomplete combustion of the mixture. In this case, the fuel, on the contrary, is too much and the mixture is excessively dense.

Spare parts for motorcycle repair and adjustment of the carburetor motorcosa.

STIHL, Makita, Husqvarna and others tuned with adjusting screws. Sometimes the reason for disrupting the work is a violation of fixation-due to vibration or damage to the protective cap. Such a breakdown can be found only by trying to turn the screw a little: if the fixation is not stiff, it is worth checking the setting.

Do.it.yourself carburetor adjustment

The setting of the module does not apply to the repair and the change of spare parts is not required. In this case, the armored complex of the carburetor of the lawn mower will not be needed.

• L. is regulated first, as it is responsible for supplying fuel at low speeds;
• H. he is responsible for supplying gasoline at high speeds, as well as for fuel consumption and temperature;
• T. with it, the idle speed is debugged.

There are options, as a rule, this is a carburetor of a Chinese lawn mower, when only one screw remains for debugging on the case. to configure idle. This does not mean that the module is configured automatically. this means that even such a type of repair as debugging will be difficult to carry out. In the photo. adjusting the carburetor of the Chinese lawn mower.

• The module tuning is carried out only with a heated engine: for this, the device is pre.included for 10 minutes. If the mowing head rotates at idle, then they begin to debugged immediately: turn the screw T counts the clock until the rotation stops.
• Adjustment starts with a screw l. The screw turns to the right and to the left until it finds such a position in which the idle speed does not become maximum.
• Then the screw is turned on ¼ turn against the watch. This will be his working position.
• The idle stroke must be configured by turns against the sentry to increase the number of revolutions and the clock. to reduce. Its debugging consists in achieving such a regime in which a sufficient number of revolutions are performed before the rotation of the mowing head. In this case, the engine should operate steadily at different positions.
• The position of the screw L is determined by the latter. at maximum speed the trimmer for grass should not work for more than 10 seconds. The throttle opens, the screw is closed clockwork, very slowly, until a decrease in the number of revolutions is established by ear.
• Then also slowly the screw rotates against the sentry until the engine starts to work with failures. After which the screw is on the time, until the engine again works normally.

If there is a tanometer, and if the product is indicated in the product passport, coooreecration can be carried out more accurate, focusing not by ear, but on the testimony of the device.

A lawn mower or a trimmer for ICE grass requires not only a constant refueling of the fuel mixture of gasoline with oil, but also periodic adjustment of this fuel supply. The carburetor is responsible for the supply of fuel to the lawn mower cylinder, the effectiveness and performance of the tool depends on the good operation of which. If in the process of operation a faulty (abnormal) engine operation is detected, then the first step is to adjust the carburetor of the lawn mower. Before setting up a carburetor of a gasoline trimmer for grass, we will first figure it out with its design.

Varieties

Currently, the Champion brand is available two main varieties of trimmers:

Electric models with a battery, unfortunately, are not produced by the company. All products are equipped with a coil of a proprietary cutting fishing line and a belt with a hip system. Consider the range of trimmers “Champion” Read more.

What will happen if you fill in the surgery in the chainsaw

If you do not want your chainsaw to refuse at the wrong time, use exclusively high-quality fuel and lubricants. Mixing with gasoline is prohibited. The reasons for this are the following factors:

• Another viscosity of the material, therefore, working out is not able to provide effective lubrication of rubbing parts and mechanisms
• The development contains small particles of metal and chips, which getting into the tank, will result in clogging the fuel filter and channel. If the lubricant enters the cylinder along with small particles, then they will leave their mark in the form of accelerated wear of piston rings
• Highlighting a large amount of black smoke, which indicates the combustion of oil

Surrogate materials cannot be poured not only in a tank with gasoline, but also in a tank for lubricating the chain. What will happen if you use working out in the tank for lubricating the chain, you can see on the video.

Using the instructions, you can independently prepare the correct fuel mixture on which the chainsaws will work. With improper dilution of the fuel mixture, not only the resource of the tool is reduced, but also its performance is reduced.

Publications

I served for a long time and did not deliver problems with the repair, you need to correctly prepare the fuel mixture. Internet forums are replete with questions on this topic. We interviewed experts and made a brief instruction.

To prepare the fuel mixture, use AI-92 or AI-95 gasoline. A lower octane number is not suitable. Gasoline is necessarily not ethyled (otherwise the engine will fail) and not old (octane number can change over time). It is forbidden to use oil for boats and four.stroke engines.

Mix gas and oil in a strictly defined proportion. Choose synthetic oil for two-stroke air cooling equipment API-TB or API-TC class. Do not save on ingredients. Ask in stores trademarks leading in quality. For example, Stihl, Husqvarna, Nanoeche, Champion, Alco, etc.

The main question is the proportion. Excess oil will lead to the formation of soot on pistons and candles. Excess gasoline will cause the appearance of bully on the pistons and an ambulance of engine. On average, one liter of gasoline is mixed with 20-50 ml of oil. Stihl and Husqvarna, for example, recommend taking 100 ml of oil for 4 liters of gasoline. The specified proportion is optimal for chainsaws up to 1.5 kW. For chainsaws with a capacity of more than 1.5 kW of the same brands, use a 1/50 proportion (100 ml of oil per 5 l of gasoline). Recommendations from Partner and Jonshed: 1/33 proportion (3.3 l of gasoline 100 ml of oil). Super synthetic oil is added at the rate of 100/1. These numbers are approximate. Always use the data given in the instructions for a specific chainsaw model. Trust the numbers indicated on the oil labels to the lesser extent.

What to mix? Kanisters with measuring divisions and two holes are presented on sale. for oil and gasoline. Pour the ingredients, tighten the lids and mix, tilting the container.

Many use glass and plastic bottles, children’s horns and syringes. Be careful with glass and plastic, be afraid of static electricity. Make sure that solid particles or drops of water do not get into the mixture. Be sure to thoroughly mix the mixture.

Ready fuel cannot be stored for more than 25-30 days, t.to. The process of oxidation changes its composition. Engine breakdown caused by overexposed fuel is recognized as non.warranty. The amount of the repair reaches 80% of the cost of the new chainsaw. After the end of the working season, use the remaining fuel, drown out the engine, remove the remaining fuel mixture.

Remember, your goal is to create a mixture that will ensure the uninterrupted operation of the engine, the complete combustion of fuel without the formation of soot, smoke or bullying.

Two.stroke engines, despite their imperfection relative to four.stroke structures, are still massively used on many newly produced devices.

• Basically, motors of this type are used for:
• Motorcycles of small cubot, snowmobiles, mopeds;
• lawn mowers, motor blocks, portable generators, chainsaws;
• motor boats;
• other devices where a small size is required with a high power.

The device of this engine imposes some features on operation. In particular, the usual lubrication system on most designs of two.stroke ICE is missing.

There are modifications where the lubricant is supplied directly to the flow of the fuel-air mixture from a special device in the form of oil fog. However, the vast majority of oil for modern 2-stroke engines enters the cylinders along with fuel.

Setting up a carburetor of a lawn mower with three adjusting screws

Before starting work, you need to place the lawn mower on a flat stable surface. Remove the chain in the opposite direction. There are motorcycles with two and three adjusting screws. Two screws most often equip the tools produced in China. Consider the adjustment of the carburetor Motokos with three screws.

Setting up a carburetor of a lawn mower with three adjusting screws

Before proceeding with the adjustment of the carburetor of the lawn mower, you need to rinse the air filter. Cleaning is carried out with water with a detergent or soap, and if necessary, a new. Often in the poor work of the carburetor, scibberries are guilty. In order to prevent the filter, it is recommended to clean the filter after every 10 hours of operation of the tool. Do not forget to check the condition of the candle, if there is a dozen, you need to clean it. Candles are consumables and have their own resource. To ensure good operation of the engine of the lawn mower, candles periodically need to be changed. Next, we evaluate how well the carburetor is fixed to the cylinder-piston group. After the preparatory manipulations are completed, you need to start the motor. Let the engine work for 5-10 minutes. Then you need to identify how many adjusting screws on your tool.

There are the following adjusting screws on the gasoline trimmer:

Fuel supply adjustment

At first you need to slowly tighten the screw adjustment screw for the fuel mixture. You need to do this until the engine starts to stall or stalls. Following this, if the engine did not stop working, you need to turn the screw for a quarter of turnover, and if it stalled, then by half the turnover. Next, you should have a stalled engine. Then you need to open the throttle and see how the speed is gaining. Turn the screw for a quarter of turnover again. You need to scroll until the engine begins to confidently gain increased speeds during cuffing. This is the right time when the engine works most economically. There are times when adjusting this screw does not give anything. Often the reason is in the factory spring that is located on this screw. This does not happen to all the tools. And if the spring turned out to be defective, then replacing it will not be difficult. A suitable spring can be purchased at any construction store.

Cooper adjustment

Following the adjustment of the fuel supply, we are accepting for the adjustment of the idle. To do this, you need to adjust the corresponding screw so that the engine works slightly accelerated at small speeds. But it is necessary to trace, for the immobility of the reel with fishing line and knives. Before the start of their movement, several revolutions should remain in stock. The movement of the coil and knives can subsequently lead to the rapid wear of the clutch. Having noticed that the engine starts poorly, you need to increase the number of revolutions at idle. With an increase in revolutions, the fuel mixture is saturated with air, which leads to power loss.

The main signs of the proper idle work:

• Revolutions for a trimmer head;
• Uninterrupted operation of the engine even when the position changes (sharp rise or descent of the knife);
• Calm operation of the engine at a cold move;
• Lack of increased speed of hot engine.

Maximum speed adjustment

Further, for the full tuning of the carburetor of the lawn mower, it is necessary to adjust the maximum speed. It will not be superfluous to look into the instrument operating manual and see the maximum speed value. This amount will help to determine the tachometer most accurately. If such a device was not at hand, we set up by ear. Barely determining the maximum speed of revolutions by ear, we begin adjustment. A screw for limiting maximum revolutions will help in this matter. Control the engine operation at maximum speed. If necessary, reduce speed, weaken the fixing nut and unscrew the screw. If the turnover is too large, then you will need to screw the screw. These actions must be done in order to protect the engine from overheating. Scroll the screw until the clear even operation of the engine is established.

After the work done, if everything is done correctly, the stable work of the tool is provided.

Understand this by the following signs:

Carburetor adjustment

Before adjusting the carburetor, rinse the air filter. It is recommended to rinse it after every 10 hours of work. After that, you can proceed to adjustment. The photo shows a carburetor of a gasoline trimmer for PRorab-8406 gasoline. The numbers indicate the adjusting screws that we will use.

Adjusting screws of a carburetor of a gasoline trimmer for PRorab-8406 grass

Make a lawn mower and wait until it warms up.

Check, opening the throttle, as the engine is gaining momentum. Continue to turn off the screw for a quarter of turning until the engine during the frying begins to confidently gain increased speeds. This will be the moment of the most economical stable engine operation. In the gasoline trimmer for PRoraB-8406 grass, adjusting screws are wrapped clockwise, unscrewed-against, in some other brands there may be the other way around.

We start adjusting small revolutions. The screw limits the return movement of the throttle lever. wrapping it, we increase idle speed, unscrewing it. reduce. Adjust so that the engine works confidently at low speeds and even a little accelerated (for better starting), but so that the coil with a fishing line or a knife does not rotate, and before the start of their rotation there is a sufficient supply of revolutions. If the engine is poorly starting, still increase the speed at idle.

After adjusting the supply of the fuel mixture and small revolutions, check how the engine of the lawn mower will work at maximum speeds. If necessary, limit the maximum speed to the required level using a hollow screw, weaken the fixing nut and screw the screw to reduce maximum revolutions or turn off to increase.

In the future, it may be necessary to adjust the carburetor of a trimmer for grass. For example, if the engine when working at full load begins to gain speed poorly, unscrew the screw by another quarter turnover. In case of difficulty starting, increase idle speed. Both weather conditions and the quality of the fuel mixture can influence work. From vibration, the adjusting screws themselves can be cream.

DIY diagnostics and adjustment with your own hands can take only a few minutes.

To do everything right, run the motor. Your actions are as follows.

• Find limit speed at idle. To do this, unscrew the screw l to the right, and then to the left. Turning step. a quarter of turning counterclockwise.
• Using the screw t, you can configure the idle speed of the motor: increasing when rotating the screw clockwise, decrease. on the contrary. The adjusted engine confidently works without load and without warming up. Heated. does not overestimate the moment.
• If you set up not a motorcycle, but a trimmer for grass, then the rotor of the screw t sets a greater margin of turnover per minute. For devices of both types, stable turns are set when choosing a mowing height with a knife (or fishing line).
• The last rotate the screw h. He sets the rate of supply of gasoline with air at maximum speed, engine power, motor heating temperature and fuel consumption.

We offer to familiarize yourself with nolina pruning to configure the motor from the screw h, make the following.

Open the throttle and squeeze the gas at maximum speeds. Twist the screw h clockwise until the engine speeds are reduced. Twist slowly the same screw counterclockwise until the engine gives out unstable speeds. Take the screw back a little (clockwise) until the engine earns smoothly

It is important to catch this line. The result of the exact adjustment is the complete combustion of fuel and the white-brownish color of the spark plug

The candle flooded with gasoline is much darker than the unbearable

Common malfunctions of carburetors

Damage of the carburetor of the trimmer for grass occurs due to the use of poor quality gasoline, damaged air filter and the accumulation of dirt in the chamber of this block. Most often, it is quite possible to repair a carburetor with your own hands. Below listed typical malfunctions of the carburetor motorcosa.

Problems of the fuel pump

A common malfunction that “pursues” the fuel pump is a deformation of the pump membrane. For this reason, it does not fit properly, and the pumping canals are not compacted.

The reasons for the deformation of the membrane can be as follows:

As a result, damage to the membrane reduces the productivity of the pump, and, as a result:

• the flammable mixture is impoverished;
• The engine is difficult to launch;
• interruptions in the work of the motor appear;
• The piston is damaged.

Also, the above consequences for the engine can cause clogging of the pump cavity from the pulse side. In this case, dirt enters the membrane through the pulse channel.

To eliminate clogging, you will have to disassemble the carburetor and clean the membrane.

Clogging of the mesh filter

A mesh filter can be contaminated when contaminated fuel is received through a fuel hose or a suction head that has defects. In the photo below you can see how a clean filter and contaminated (parts are separated by a feature).

To eliminate the malfunction, thorough cleaning and flushing of the mesh filter will be required. It is also recommended to blow with compressed air all holes in the body of the carburetor trimmer for grass.

The adjusting lever is faulty

This breakdown appears when the contact surface of the lever wears out.

Washing the contact surface occurs due to the presence of abrasive particles in gasoline or due to strong vibration of the motor during operation. This defect in the adjusting lever causes problems with the inlet, as well as incorrect operation of the motor at idle.

Wear of the intake needle

The inlet needle fails, as a rule, due to the presence of abrasive particles in the fuel fluid.

• The insurance of the saddle of the intake needle is violated;
• the leakage of the combustible mixture appears;
• malfunctions in the operation of the engine associated with re.enrichment of the fuel mixture appear.

Also, the intake needle can simply jam.

Singing an intake needle can cause the presence of dirt in a combustible, or a long simple apparatus without work.

Clogging of the adjusting cavity

If dirt accumulates in the adjusting cavity, then the inlet needle cannot lock the hole tightly and a lot of fuel pours into the chamber.

This causes fuel rewriting, and the engine begins to work incorrectly. It is necessary to disassemble the carburetor and clean the cavity of the adjusting membrane.

Deformation of the adjusting membrane

The membrane may be deformed with prolonged operation of the unit and when using aggressive fuel.

The impossibility of normal adjustment due to the defect leads to:

The problem with the intake adjustment lever

This problem may occur if the adjusting lever is incorrectly, or bend it before installation. As a result, the contact surface takes the wrong position, which violates the additional fuel supply.

Damage to the damper

Throttle and air shutters basically wear out due to the presence of abrasive particles in the air. Defective shutters look as if they were subjected to sandblasting.

As a result of wear of the damper, the engine performance decreases, malfunctions appear in its operation, piston rings, piston and cylinder coating wear out.

Wear of the throttle and air damn

The shaft of air and throttle can wear out for the following reasons:

• insufficient and incorrect air filter maintenance;
• The air filter is damaged;
• The air filter is unsuitable for this device.

Due to the ingress of poorly purified air, the shaft wears out and may break. The broken parts of the shaft can fall into the combustion chamber or the engine of the engine and cause serious damage to the entire piston system.

To eliminate problems with air purification, it is necessary to replace a defective filter or rinse the existing (working). The filter must be washed in soapy water and dried.

Then you need to open the throttle and see how the speed is gaining. Turn the screw for a quarter of turnover again. You need to scroll until the engine begins to confidently gain increased speeds during cuffing. This is the right time when the engine works most economically. There are times when adjusting this screw does not give anything. Often the reason is in the factory spring that is located on this screw. This does not happen to all the tools. And if the spring turned out to be defective, then replacing it will not be difficult. A suitable spring can be purchased at any construction store.

Cooper adjustment

Following the adjustment of the fuel supply, we are accepting for the adjustment of the idle. To do this, you need to adjust the corresponding screw so that the engine works slightly accelerated at small speeds. But it is necessary to trace, for the immobility of the reel with fishing line and knives. Before the start of their movement, several revolutions should remain in stock. The movement of the coil and knives can subsequently lead to the rapid wear of the clutch. Having noticed that the engine starts poorly, you need to increase the number of revolutions at idle. With an increase in revolutions, the fuel mixture is saturated with air, which leads to power loss.

The main signs of the proper idle work:

• Revolutions for a trimmer head;
• Uninterrupted operation of the engine even when the position changes (sharp rise or descent of the knife);
• Calm operation of the engine at a cold move;
• Lack of increased speed of hot engine.

Maximum speed adjustment

Further, for the full tuning of the carburetor of the lawn mower, it is necessary to adjust the maximum speed. It will not be superfluous to look into the instrument operating manual and see the maximum speed value. This amount will help to determine the tachometer most accurately. If such a device was not at hand, we set up by ear. Barely determining the maximum speed of revolutions by ear, we begin adjustment. A screw for limiting maximum revolutions will help in this matter. Control the engine operation at maximum speed. If necessary, reduce speed, weaken the fixing nut and unscrew the screw. If the turnover is too large, then you will need to screw the screw. These actions must be done in order to protect the engine from overheating. Scroll the screw until the clear even operation of the engine is established.

After the work done, if everything is done correctly, the stable work of the tool is provided.

Useful material from which you will learn how to get a capricious gasoline trimmer for grass that does not want to work!

The summer time has come, and in the personal plots habitually hidden the lawn mower. Great tool, powerful and mobile.

However, there are cases that the lawn mower does not start, works with interruptions or without developing full power. Of course, no one is at work! And as they say, you twitch the laborer’s handle more than the mowing.

Difficulties with the launch do not only have the types of motorcycle, but also in new. How to be in this situation? There is only one way out. to listen to the advice of experts and take advantage of their practical experience!

The device of the carburetor of the lawn mower

The standard design of any gasoline trimmer for grass must include a fuel system, the basis of which is the action of a standard carburetor. Its device and the initial principle of action are almost the same for all motos, regardless of their design characteristics and purpose.

The carburetor of the motorcycles consists of an entire.metal aluminum corps, which protects the internal components of the node from moisture, fine debris and dust. In the lower part of the case, a built.in diffuser is provided, the second name of which is “Venturi’s nozzle”. The main function of this regular part is the supply of air in the amount that is required by the fuel node to enrich the fuel. Diffusure work on a simple principle: the smaller its diameter becomes, the more intensively the air is absorbed. This is due to the fact that in the zone of the smallest diameter the level of air discharge becomes maximum.

The upper part of the built.in factory diffuser is pre.equipped with fuel tubes, according to which, under the influence of air, the fuel mixture is delayed. The remaining parts of the carburetor: regular adjusting screws and fuel pump can be located both inside and outside the carburetor.

The device of the carburetor Motokosa includes a throttle, the main task of which is to adjust the volumes of absorbed air. The larger the amount of air, the higher the rated power of the power unit of the trimmer for grass. Another damper function is to relieve the cold start of the engine. If the lawn mower is started for the first time after prolonged downtime, then the damper must be closed. Immediately after starting the motor, the part must be opened, otherwise the ICE will stall.

The carburetor for a trimmer for grass is equipped with a pulsed channel, which connects the internal cavity of the ICE crankcase with the pulse chamber of the pump. The piston located in the motor cylinder creates reciprocating movements, which leads to phased changes in pressure inside the crankcase. At the same time, a membrane is set in motion. Thus, the action of the pump is completely synchronized with the operation of the power unit.

A standard carburetor membrane takes an active part in the fuel suction. In the fuel node, it gets through the fitting. After that, the fuel passes through the built.in intake and exhaust valve, then through the mesh filter and fuel tube. Then the fuel flows next to the needle and gradually fills the camera equipped with a control membrane.

The standard valve of the carburetor trimmer for the grass is connected to the membrane using a lever. Below the built.in membrane is a cavity into which the air is absorbed through a special hole.

The carburetor for the lawn mower is working on this principle in stages. This ensures the continuous operation of the fuel unit and the uninterrupted supply of fuel in the cylinder of the standard power unit.
