Trimmer for grass eats a lot of gasoline what to do. Gasoline gasoline non -self -propelled – purpose and description

A trimmer carburetor device for gasoline grass

Motokosa carburetor adjustment is a process that needs to be mastered for the full operation of a trimmer for grass. Trimmer for grass is a completely simple device that can break in only a few places and demand a mechanical repair or replacement of part. Adjustment of the carburetor device of the float.type motorcycles may require knowledge of certain subtleties. The nuances due to the model and the specifics of its functioning will ensure a clear mixing and supply regime of the fuel mixture.

CHAMPION BAS carburetor, how to adjust? This is just a trimmer for floating type grass. a common option designed to mix air and fuel in the proportions provided. The main problems arising during the operation of the motor are approximately similar to the problems that overtake the carburetor in the car:

the motor can stall immediately after it managed to start. The reason is that gasoline is supplied in insufficient quantities. This is called “poor” fuel;
Excessively fed gasoline leads to its incomplete combustion, excessive density of the mixture and uneconomous consumption.

Repair of the carburetor

Important! It is necessary to regulate the carburetor under different circumstances: a change in the temperature regime, octane fuel or type of oil, after winter or end of the run.in, load or spontaneous turning of the screws from strong vibration of the body. Some owners prefer to configure the module before each use to make sure of its correct work.

The main problems

Malfunctions of the carburetor Motokos or trimmer for grass, despite the relative simplicity of their elimination, sometimes require a long search by excluding. The main reasons are as follows:

The most repeating breakdown is wear, rupture of the membrane. As a result, its lavation. Fuel moves are not sealed at certain stages of the engine cycle. The reasons here are as follows:

You have been working on a motorcycle or trimmer for too long without a break;
Poor.quality fuel was seasoned;
Wheelled gases fall into the pulse channel.

A deformed membrane is fraught with several bad consequences:

not enough gasoline or oxygen in the created combustible mixture;
the launch of the motor occurs after 10 or more unsuccessful attempts;
the engine knocks, clats during operation, and t. D.;
The working piston is deformed.

The reasons for the clogging of the mesh filter are poor.quality fuel cleaning, damage to the hose and/or the injection head.

Wear of the contact edge of the lever. a consequence of not completely purified fuel, into which grains of sand or particles of clay, metal or other inclusions that are not soluble in liquid hydrocarbons fell. A problem with fuel injection appears, the motor does not function with interruptions without load.

The inlet needle breaks due to the presence of metal and stone particles in gasoline. As a result, the saddle of the intake needle tightly adjacent to it, the fuel mixture flows. In the combustible mixture created by the carburetor, there is too much air, which is why the motor can “sneeze” during operation. Finally, the needle can stop due to poor-quality gasoline, or the unit was idle for a long time.

Deposits may accumulate in the adjustment compartment. The needle does not completely cover the hole, and a lot of gasoline enters the fuel chamber. the motor pours it, perhaps floods the spark plugs. Because of this, the gasoline mixture contains an increased number of vapor of gasoline. The efficiency falls noticeably.

The membrane is often deformed (sometimes torn) due to continuous operation of motorcycles or trimmer for grass for several hours. If you abuse such a “shock” mode of operation, damage to the membrane occurs more often. New breakdowns will be sprinkled from a cornation of abundance:

the piston will break;
The number of attempts by the unsuccessful start of the engine will increase sharply;
The fuel mixture will contain too little gasoline;
Useful (thermal) power will drop sharply.

Sequeling of the adjusting lever. a consequence of the incorrect installation, random flexion. Contactive line will find an incorrect position. This will violate the additional injection of gasoline.

The damper has worn out

Throttle and air conditioning are unusable due to admission to the air flow of dust, metal particles, etc. D. Damaged shutters are similar to details subjected to streaming with sand. Due to wear of the damper, the efficiency of the motor decreases, breakdowns are detected. The piston and cylinder wear out.

In some cases, this filter is simply not suitable for your model motorcycles or trimmer for grass. In the end, the shaft of the motor will suffer. its pieces fall into the engine channels, which is why the piston will be broken.

The fact that the adjustment is too rough (it is not possible to accurately set the parameters) are to blame for the adjustment screws. The manufacturer Motokos or trimmer for grass can put excessively thick and hard springs. You can find others either in workshops where such equipment is repaired, or purchased from any dealer or official representative of the company who released the engine for your trimmer for grass or mechanical braid for grass.

Principle of operation

The order of injection and filtering of fuel in the engine of the lawn mower is next.

With the help of a throttle, the amount of air supplied to the diffuser is set. The more air is supplied, the more oxygen needs gasoline for combustion, and the greater the power released in the form of heat. The energy of the heat is further converted into a mechanical.
The membrane pump pumps the required amount of gasoline.
Next, gasoline passes through the engine fitting.
Fuel passes through a retractable and exhaust valve.
Fuel is filtered using a mesh filter.
Through the needle valve, it also enters the camera with the membrane.

The stages of the carburetor is as follows.

Air enters the pipeline with an air conditioning. The damper sets the desired air flow intensity.
The diffuser is narrowed in the node of gasoline’s injection. this is necessary to give a higher air flow rate.
Fuel passes through the bastard compartment and passes the jet, falls into this narrowing of the tube. The float compartment doses the supply of gasoline. In this compartment, the pressure is in a state of equilibrium. In a narrowed tube, it decreases. Due to the difference in both values of pressure gasoline and passes through the jetler.
Accelerated stream sprays gasoline, converting it into aerosol pairs. The resulting gas-air mixture is ready for a rowing in the combustion chamber.
Having passed through the fuel pipeline, this mixture is in the cylinder of the carburetor.

Conclusion: To set the required power, first of all, you will adjust the rate of combustion of fuel using an air damper. If the gap is too small, and the oxygen in such a mixture is less than 10%. the fuel does not burn, therefore, the engine will not start or immediately staller.

In the case of buying a Chinese trimmer for grass, it is worth considering that it differs little from European- the same 2- or 4-stroke engine and drive.

However, the quality of the details is saved, forcing the consumer to change them more often. Check what compatible details offer non.Chinese companies for your device.

Gasoline consumption for a trimmer for grass

The lawn mower. a very simple device. There is nothing so special in it. And therefore, many buy it for their needs, since everyone can master how to work with it, and quite quickly.

Building gasoline trimmers with great hunting are bought not only by amateur gardeners, but also by professional services. When they purchase such a product, the first thing is to take into account the power of the device. This is right. However, when buying, other factors must be taken into account.

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

IMPORTANT! However, in this case, of course, the fuel tank will be large. As a result, in general, its design becomes heavy

And this will make it difficult to work. Is it possible to find a wise solution in this situation? The problem can be solved by reducing fuel consumption.

Next, we will talk about how it can be, what depends on the fuel consumption of a trimmer for the grass, and also advise which gasoline is better to choose for work.

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.

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.

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

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.

Before setting up a carburetor of a gasoline trimmer for grass, we will first figure it out with its design.

Patriot Pt 545

The piston located in the cylinder, producing reciprocating movements, sequentially changes the pressure in the crankcase or increase in pressure. The trimmers presented today on the market for ICE grass are equipped with a D-shaped, U-shaped or T-shaped handle, where the main controls of the unit are located.

The starter is necessary to bring a trimmer for grass to working condition, its diagnosis is to check the tension of the lace of the starter coil with the teeth of the coil, which are often destroyed at a sharp launch. Traditional braids for grass are inconvenient and unsafe in use, require significant expenditures and their own forces that will help to save law mowers that combine functionality and practicality in their design.

Solving complex problems Huter GGT-1500SX

Which trimmer for Patriot grass is better to choose according to the owners of the owners in most models of the fuel supply propelled screw on the fuel supply screw clockwise, but there are trimmers for grass, where the decrease and increase in the intake of the mixture occurs in the reverse order. The base of the throttle, inlets and exhaust valves, the joints of all parts of the carburetor can be checked with a simple effect, grease the problem area with soap foam.

Knowing the internal device and the principle of operation of the trimmer for grass, you can independently carry out repair measures for the design or replace individual unusability of the nodes using the repair instructions.

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:

Compare. gasoline and electric trimmer. which garden tool is better to choose?

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 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.

Here’s how you can calculate how much fuel is your car.

If you want to know exactly how much gasoline or diesel fuel consumes your car, you can use the fuel consumption calculators in the web (there’s a lot of them now) or simply calculate the fuel consumption using a conventional formula without the help of others. First you must fill the fuel tank of your car is one hundred percent. Then you should reset the day mileage on the dashboard. If you do not understand how to do this, find the annotation in the management of the car or find the info on the network.

Typically, in almost all cars, the button for the zeroing of the day mileage (do not confuse with the main kilometer meter. by a car with a car that cannot be reset) is specifically under the dashboard or directly on it. In some cars, the Khully Kilometer Knocking Pour button is placed on the steering wheel lever. There is also a car where to zero the daily run of the car, you need to drop the testimony of the day odometer through the menu of the car options.

So, having dropped the meter of the daytime run, you must drive several hundred km to find out exactly how much your car consumes fuel in essence. By the way, for this for you there is no need to burn a full fuel tank. For a clear calculation of the real use of fuel for you, you need to drive 200-300 km.

Advice. Drive the car in the same way as in daily life. For example, not only moving along a high.speed highway. So you will not calculate the real fuel consumption, since at least what a car when driving along high.speed highways in the city consumes even less fuel than in the town. Therefore, your test route for fuel measurement should include trips both in the town and on the highway. If in most cases you operate a car in the town, then with a test route use a car of 60-70 percent of time in urban traffic. In 30-40 percent of cases, you can use the car on the highway.

After you pass several hundred km, return to the gas station and again completely fill the fuel tank. In order to calculate the real consumption of fuel (and not the one indicated by the on.board of your car, the values of which are far from reality), you should know how much fuel was spent during your test race and the number of km on the daily odometer, which you had to previously Knock. Here is the formula for calculation:

number l. The fuel that you have set up: how much did you drive X 100 = fuel consumption in l / 100 km

Here are two examples for calculating the fuel consumption according to this formula:

For example, imagine that we, having tucked a full tank with a volume of 50 liters., We drove 517 km. Further, when the light bulb on the tidy warning about the small level of fuel caught fire, we again arrived at the gas station for refueling. Taking into account the small amount of fuel remaining in the tank, we again tucked the car until the full tank. Ultimately, 48.7 liters of fuel entered the tank. Now, knowing how much fuel was spent by a car (48.7 liters) and a mileage on a daily odometer (517 km), previously dropped to measurements to zero, we can calculate the real consumption of our own car according to the above formula.

In the 2nd example, we calculate the consumption of a combustible car with a small run. In other words, during the run is not up to the moment when fuel is already completed in the tank. Imagine that you are 50 liters of bay. fuel (full tank) and having relying the daily mileage of a car, 300 km drove. Then again we drove at the gas station and tucked the car to the full tank. Ultimately, 28.2 liters entered the tank. Now, knowing the mileage (300 km) and the amount of fuel spent for this run, according to the above formula, you can calculate the clear consumption of the fuel of your car. Here is the calculation:

You see, with the lowest run, we received the same fuel consumption as with more. That is why, in order to accurately measure the consumption of fuel with your car, you do not have to burn the whole fuel tank. To do this, just drive only a few hundred km.

The lawn mowing engine does not want to start after winter

One of the main reasons that after winter the lawn mower is not started. stagnation of fuel in a gas tank. If you do not drain the fuel from the tank, and leave the tool to store for a long time, then it will naturally be impossible to start the lawn mower. The properties of a mixture of gasoline with oil fall, so as a fact we get a tool malfunction. Even if the fuel mixture has remained in the trimmer last year, it is recommended to drain it, and pour freshly prepared. After that, start the tool.

Another cause may be a malfunction of the air damper. When closing it manually, the valve itself may not work, so you start the lawn mower with a completely open air damper. In this case, the tool will not start the cold, as there is a large air leak. The video below tells why a trimmer does not start for grass for cold.

In addition to these reasons for the impossibility of starting the gas mowing engine, there are others, which are also important to mention:

Disciplings of the Electrodes of the candle. before starting the trimmer for the grass after winter, you should twist the spark plug, inspect it, clean, dry and set the gap
Damage to the high.voltage wire. During the storage of the tool, the high.voltage wire could crack, damage or could gnaw the mice. Make sure the integrity of the armored pipeline if the trimmer for the grass does not start after winter
Oxidation of wire contacts. This usually happens if the tool is stored in a room with high humidity
Check the serviceability of the ignition coil. During the winter, this detail could fail, and cause a difficult to launch the tool
Carburetor adjustment. it is recommended to configure the carburetor after the winter. To implement this, the tool should start, therefore, if it is impossible to start, it is recommended to pour 20 grams of fuel mixture into the candle hole, and launch the motor
To perform all the above actions, since during a long.term storage the hole of the saapoon, filters, as well as corrosion on the walls of the exhaust system could form

Diagnose the tool, and only after that resort to a more serious repair. cleaning the carburetor.

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. Using a gasoline trimmer for grass and grass, you can mow, and get rid of a dried.up weed. 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.

Work principles

If the drive of the lawn mower is electric. use it is a pleasure. Not only men, but also representatives of the weaker sex, and even people of advanced age easily cope with the management of garden equipment.

A wide range of oils, which are part of the mixture: gasoline-oil for the lawn mower, as in the photo, is presented in the selling stores. For the manufacture of such a fuel mixture, a canister with five liters of gasoline is taken, one hundred milliliters of oil are added, shaken and poured into the gas tank. It is not necessary to buy oil with the same name of the manufacturer of the mower.

Gasoline consumption rate for a lawn mower

Let us consider as an example several indicators for well.known models. For such a lawn mower as AL-KO Silver 520BR, endowed with the Briggs Stratton engine (3.7), norm. 1 l/mash.-hour. For Honda HRX 426C SDE with a powerful Honda GCV-160 (4 Honda.1). 0, 8 tank l/mash.-hour.
