How to correctly configure a motorcycle carburetor. How to properly adjust trimmer adjustment

Many masters use benzocouses for a long time, and at the same time do not think about the need to adjust the carburetor of the tool. When it is necessary to adjust the carburetor on a benzocos or motorcycle? If you ask such a question, then changes in the work of the motor are probably not for the better. In order not to guess, and not to miss the moment of the need to configure the carburetor, you should adhere to the following recommendations on the need for adjusting measures:

  • After passing the Typically, the running-in lasts over the burning of 4-5 liters of fuel
  • Когда в бак заливается топливная смесь другого состава, то есть меняется тип масла (даже его цвет) и марка бензина
  • When changing weather conditions, however, this is relevant more for chainsaws, gas generators and motorcypts, which are operated not only in the summer, but also in winter
  • If the lawn mower was not used for a long time. The reason for the need to adjust may be a winter break
  • When fuel consumption increases
  • If black fog on the electrodes of the candle is detected
  • In the absence of gasoline from the cylinder or poor engine start
  • If a large amount of exhaust gases are detected
  • Unstable engine operation, as well as its difficult start and a “sluggish” set of revolutions

As you can see, there are enough reasons for adjusting the carburetor. Typically, masters who work for a long time for a long time, find changes in the operation of the motor, which promises the need to conduct an adjustment process. Even if they are not sure of the need for adjustment, then their extraordinary execution will definitely not be superfluous.

Launching the motor

The engine starts at a distance of 3 m and more from the place of refueling the device with fuel. These works cannot be done in a closed room. To you need to take a stable reliable position. Motor management is held very tightly with all this. The cutting tool should not come into contact with the ground or objects, because when starting it can spin.

The unit is served only by one person, with all this, persons in the zone with a radius of up to 15 m should not be. In an unpleasant case, you can get an injury due to discarded items. Starting of the Stihl FS 55 lawn mower, the properties of which are presented in the article, should not be by hand. The cutting tool after releasing the gas lever will move for some time by inertia. Flaming materials must be kept away from the hot stream of gases and the surface of the hot silencer, because this can become a prerequisite for the fire.

How to set up a lawn mower carburetor to work better, and fuel eats less

Get one most read article by mail once a day. Join us in and

Nowadays, the word “carburetor” is familiar mainly only to those who have yet found cars with the corresponding engines in their memory. At the same time, carburetor power units are universally used in a variety of agricultural machinery for giving. Just get into an important detail with a screwdriver, few will dare to imagine it with a sort of “sacred cow”, which is better not even to approach. And in vain.

In fact, a carburetor is a fairly simple device. The same can be said about its configuration. There is nothing out of place in this matter, especially when it comes to garden technology. Equipment adjustment options, in fact, only two: setting idle revolutions and setting up a mixture of gasoline and air. Both calibrations are carried out by carrying out manipulations with one of two bolts. Most often, the setting of the supplied mixture is made using a thick yellow screw, and the idle calibration is sold using a thin white screw.

Before performing any manipulations with a carburetor of any garden tool, the engine first needs to be turned on for several minutes and warm up. In this case, the damper regulator must be put into a position corresponding to the work regime. Immediately after warming up the mechanism, the screw that is responsible for the quality of the air-banding mixture is twisted so that the idle speed of the tool begins to fail. The motor may stall.

Next, the screw is unscrewed from the reach of the half-turn in the opposite direction. We give full gas, if the tool engine did not stall and did not begin to zoopet, then everything was done correctly. If nothing has changed, then the mixture screw is unscrewed by another quarter turnover, behind this is again the check and so on until the victorious end. We can check the result of prolonged gas without fail. the lack of cotton, zabulak, and extraneous noise will confirm success.

The next thing that can be done to set up a trimmer for grass is to set a suitable idle parameter. The principle of adjustment here is exactly the same, only now we work with a thin white screw. On a heated engine, we tighten it to a state of zabovki of the unit when pressed on the gas, after which we begin to gradually release. First to the turnover, then half, then a quarter. until the tool starts working normally and without obvious interruptions.

The correct calibration of the revolution screw will reduce the amount of fuel consumed, and the competently set the mixture screw. increase the capacity of the tool. By the way, the details about the setting are contained in the technical leadership, which was supposed to be included with the acquired garden tool.

Winter is no longer around the corner, and therefore it should be read about what a real cleaning mechanization is: how to make a snowball player from a trimmer for grass.

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:

Flamming fuel supercharger

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.

Carburetor vs Fuel Injection. Why Motorcycle Riders Should Think Again

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.

As a result, the internal space of the fuel pump is contaminated from the side of the pulse channel.

Ground of a mesh filter

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

The failure of the adjustment lever

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 is spoiled

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.

Clogging the adjusting space

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 adjustment membrane is spoiled

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.

The inlet regulatory lever sees

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.

The shutters become unusable due to incorrect service of the air filter or its breakdown.

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 carburetor cannot be adjusted

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.

The primer broke

Primer-a manual mini-pump for forced swinging fuel into a carburetor. For a successful start of the motor, it may be necessary to pump 20 ml of gasoline manually.

Elimination methods

The list of upcoming work with the engine may be as follows:

  • replacement of the fuel pump;
  • disassembly and flushing of the mesh filter;
  • replacement of the adjusting lever;
  • It is also necessary to clean the adjustment space;
  • replacement of the membrane (or the entire block where this membrane is located);
  • setting in intake, graduation and needle valves;
  • replacement of the damper;
  • cleaning the fuel channels and diffuser;
  • replacement of springs of screws;
  • Change of primer.

Not all these works can be completed. It often turns out that many of them have no need if a specific malfunction is immediately discovered.

Carburetor for a trimmer for grass. How to adjust the carburetor of a trimmer for grass.

On trimmers, in addition to electric motors, gasoline internal combustion engines are installed. This mechanism requires special attention, since if it is incorrectly set up, it will either refuse to work or work with interruptions and power loss. Basically, the engine setting is to adjust the supply of fuel, and this is done using a trimmer carburetor for grass.

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 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 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 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 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.

Когда требуется настройка карбюратора бытового триммера для травы? It is necessary to adjust the carburetor of a trimmer for grass with:

  • running a new engine, during which from 4 to 5 liters of fuel mixture were used;
  • sharp changes in the weather;
  • changes in air vacuum. for example, when a lawn mower is often used in mountainous areas;
  • prolonged simple trimmer for grass;
  • intensive growth of loads on the power unit Motokosa;
  • arbitrary twisting of the adjusting screws of the carburetor. this becomes the cause of increased vibration of the internal combustion engine;
  • change in the quality of the components of the fuel mixture;
  • transfusing a fuel by a carburetor, a result of which is an increase in fuel consumption;
  • the regular appearance of the thick layer of tarry deposits and soot on the surface of the electrodes of the standard spark plug of the trimmer for grass;
  • starting the engine and its arbitrary shutdown or slow speed;
  • lack of fuel intake into the cylinder of the power unit;
  • increase in the volumes of ejected gases.

The lack of timely tuning of the carburetor threatens the serious breakdown of the trimmer for the grass, up to the full failure of its factory engine. carburetor adjustment. Periodic adjustment of the carburetor of the trimmer for grass should be performed on the served and completely serviceable power unit. Before starting the procedure, the operator must thoroughly rinse the details of the internal combustion engine and inspect its CPG for the presence of burrs or other defects. In addition, you will need to clean or change the spark plug, as well as rinse the filter elements in the design of motorcycles.

During the tuning of the carburetor, the engine of the lawn mower should operate under a certain load. It is best to install a cord of the corresponding diameter or cutting knives on a trimmer for grass.

After the installation of the cutting organs, the operator must start the ICE of the trimmer for the grass and leave it to work for about 10 minutes. If during the operation of the power unit at idle, it was noticed that the cord or knife rotates, then it is necessary to reduce the speed created by the engine. To do this, turn the lower regulator, often indicated by the letter “t”, to the left side, until the installed cutting organ is completely stopped. The further settings of the fuel node are as follows:

  • The “l” regulator, located on the right, is responsible for the enrichment of the fuel mixture by air during the operation of the motor at low speeds. The position of this screw must be configured first. To do this, the operator will need to achieve maximum engine speed when working at idle. for this you need to alternately turn the “l” screw in the right or left side. As soon as the maximum revolutions are achieved, the screw will need to be turned to 1/2 turning to the left;
  • The screw “t” or “LA” is necessary to adjust the idle. During its turning to the left, the power unit will decline, and when turning to the right, respectively, increase;
  • The H “H”, provided on the left, is responsible for the enrichment of the fuel mixture by air during the operation of the ICE of the Trimmer for high speeds. This screw is also needed to configure the power of the motor and the volume of the consumed fuel. The setting of its position is carried out by turning the screw to the right or left sides until the maximum permissible engine speed is reached. After that, the screw “h” will need to turn 1/2 turn to the left.

You can adjust the carburetor of the lawn mower with your own hands

lawn mowers, like the entire bench tool for the garden, is not difficult to maintain equipment. Repair, set up on your own and it is necessary. For example, adjusting the carburetor of the lawn mower with your own hands is the matter of five minutes.

The carburetor from the lawn mower is a node in the power supply system. In it, like any carburetors, there is a process of mixing air and fuel (gasoline) for further supply to the motor cylinders.

In this process, the main thing is the correct proportion of fuel and air, for which the carburetor is regulated.

The main problems and malfunctions of the carburetor.

Mesh filter. There are only two problems with this element more often:

In order to find out the cause of the breakdown, the fuel filter lid is unscrewed to extract the mesh filter. If dirt just accumulated on it, then flushing in gasoline or purging will help.

With visible damage on the mesh filter, you must definitely put a new. There may also be damage to the fuel supply pipe (during the repair they practice checking this element).

The starting device of the carburetor in most cases does not function due to blockages. Should be used for flushing acetone or the same gasoline.

Purging parts of a carburetor with click of compressed air. permissible and convenient repair practice.

The hull of throttles, the ligaments of the parts of the carburetor, the intake or graduation pipeline. all of the listed parts are subject to depressurization. You can probably check in a primitive way. spread the problem area with soap foam.

The spring may interfere

My first attempt to adjust the gas mowing carburetor did not give anything, since the spring of the fuel mixture adjustment propeller prevented. The factory spring turned out to be too thick in a compressed state and did not make it possible to reduce the supply of fuel to the required level. I had to choose another spring and continue the adjustment after its replacement.

The adjusting screw for feeding the fuel mixture with the spring

In the photo above the factory spring, below the adjusting screw with a selected spring. I am writing about this, because I am not sure that this is an isolated case, and someone else may face the same situation.

Malfunctions and their elimination

Electric and gasoline trimmers have typical breakdowns and malfunctions. For devices running from an internal combustion engine, this is:

  • problems in the carburetor;
  • engine breakdown;
  • problems with the fuel system;
  • breakdown of the gearbox, starter, muffler;
  • blockages;
  • Air filter breakdown;
  • Problems with ignition coil.

Electric units have specific breakdowns:

With simple problems, you can make a trimmer repair for grass with your own hands.

Why is a trimmer not starting for grass

The most common reason that the unit does not start is the use of poor.quality fuel. The choice of gas stamps below AI-92 can disable the lawnical mower. If high.quality fuel is used, you need to look for other reasons. To do this, carefully check all nodes and systems. The checks are subject to:

The device may not start after prolonged downtime. Before turning on a trimmer for grass, you need to study well the instructions for operation. The solution of many problems is indicated in it.

If it stalls when you press the gas

There are several reasons why a trimmer for grass stalls when gas is pressed:

  • The first reason is the dumping of the carburetor.
  • Fuel valve.
  • Fur valve blockage.
  • The weakening and sagging of the carburetor cable or sagging of the fuel intake hose.

So that the described problems with the lawn mower do not arise, you need to carefully monitor the condition of the device and its blocks. Timely cleaning, washing of the unit and spare parts allow you to increase its life.

Starter breakdowns

The most difficult breakdown of the starter occurs when the rope is broken and winding it into the flywheel of the operating engine. As a result, the spring may burst and the pulley plunges. In this case, only a complete replacement of the spare part will help. This breakdown rarely occurs. often:

In this case, it is easy to fix the starter yourself. The manufacturer has prepared a instruction for this.


Caring for the motorcade gearbox consists in the timely lubrication of the unit. The absence of one can lead to rapid wear of the gear and jamming of the gearbox module.

The main malfunctions of the trimmer gearbox for grass:

  • severe heating of the gear component due to the use of low-quality lubrication or its absence;
  • shaking of the shaft during the rotation of worn bearings;
  • staggering or flowering from the bar of the gear ratio as a result of damage to the case;
  • Lack of rotation of the output shaft with a knife due to wear on the teeth on the gears.

This happens due to the use of low-quality lubrication or its complete absence. Another reason for the failure of the gearbox is the operation of a trimmer for grass at the limit of its capabilities and the hit of foreign objects. To replace a faulty bearing, a gearbox is disassembled.

Features of the repair of electric models

Electric models of trimmers operating from the network have several main blocks:

Each electrimmer block has specific problems. In the mechanical part, they depend on the presence of a fishing line used as a cutting element. Reasons for the termination of work:

You can identify the problems of the electrical part of the electrocos using special tools:

To eliminate problems, a soldering lamp is needed.

  • a malfunction of the power cable;
  • problems with an outlet and fork;
  • the failure of the control handle;
  • combustion of the starter winding, engine replacement is required;
  • Contact breaks can be corrected independently using a soldering lamp.

This is actually its own easy operation, but our clients remains to be done well in order to achieve a suitable result.

Increased fuel consumption and the rapid formation of soot on the candle mowing candle when using a properly prepared fuel mixture indicate the need to adjust the carburetor. It describes the configuration of trimmers with carburetors with one screw for adjusting the supply of fuel.

The main problems and malfunctions of the carburetor.

Mesh filter. There are only two problems with this element more often:

In order to find out the cause of the breakdown, the fuel filter lid is unscrewed to extract the mesh filter. If dirt just accumulated on it, then flushing in gasoline or purging will help.

With visible damage on the mesh filter, you must definitely put a new. There may also be damage to the fuel supply pipe (during the repair they practice checking this element).

The starting device of the carburetor in most cases does not function due to blockages. Should be used for flushing acetone or the same gasoline.

How to set a ignition on a trimmer

Often, owners of gasoline cos are faced with the fact that the ignition does not work on their equipment. In most cases, the problem is really with this knot. To fix this, you need to adjust the ignition to a trimmer for grass. But at the same time, it is not uncommon for the ignition coil to be in good condition, and a breakdown must be sought elsewhere. The ignition system is constructed equally on four.stroke and two.stroke internal combustion engines, so the elimination of the device malfunctions is performed similarly. In addition, the technologies of various brands have an almost identical design of this most important component of the tool, which means the regulation process will be the same as for trimmers a union or foreman, and for Huter, or for samples of other brands.

The basis of the carburetor of the lawn mower is an aluminum corps. It has a diffuser (hole with internal contours). Air is pumped through this hole. The speed of oxygen (air) is dependent on the cross.sectional (passage opening) of the diffuser. The diffuser is equipped with fuel channels. Fuel is drawn from them using air flow.

Carburetor malfunctions and their elimination.

The main element of the car drive system is the carburetor. Characterized by subtle setting and excessive sensitivity to various external influences. Before changing and modifying it, it is necessary to find out whether this is the cause of the engine malfunction (or its unstable operation). If it is obvious that the carburetor is faulty, then the priority task is to a visual assessment of its details. An external inspection of this part of the car will help assess the degree of damage and focus on further actions.

  • The most common carburetor problem is the lack of idle. This can be solved quite simple: just check the condition of the electromagnetic lock valve. In most cases, it flies out of the connector, causing a malfunction of the motor installation of the car.
  • Another problem that can be encountered when checking a carburetor is a high engine rotation frequency at idle. The reason may be the wedge of the throttle axis. It is located in the second chamber. Damage can be eliminated by changing the position of the damper lever relative to the adjustment screw. Simply put, this damping lever should completely close the nest in the chamber when the car is idling.

The above malfunctions are the most common. They can be removed by visual inspection, without resorting to serious intervention in the design of the carburetor. If the cause of the failure is not in this case, a comprehensive diagnosis is required. The strange operation of the car engine system at idle can be caused by a meager composition of the working mixture. This can be determined by ear. the speed will swim. If you look into the first carburetor chamber, you can see gasoline drops on its walls. The gradual enrichment of the mixture leads to the stabilization of the engine (which is also determined by the ear) and the absence of drops in the chamber.

Typical malfunction of the carburetor. transferring fuel into the float chamber.

  • Another reason for an unstable engine in the carburetor compartment (float chamber) may be a high level of gasoline. This error occurs when the foam holder fails or the valve is damaged. This can be determined by the way the warm engine starts. If the launch is difficult, then most likely you need to evaluate the fluid level in the float chamber. This is due to the fact that after stopping the engine, the fuel is under pressure (due to the operation of the fuel pump). He immediately rises into the float chamber and drowses it, entering neighboring chambers. To avoid this problem, you need to check the carburetor filter more often (it is located right under the plug). instructions for repairing carburetor motorcosa

Dismantling the carburetor

Visual inspection of the carburetor will help to identify the leakage of the fuel of the air mortgage, but the main reasons for the refusal of the device lie inside. Therefore, in order to determine and most importantly, correct the breakdown of the carburetor must be disassembled.

To disassemble the carburetor, Motokos is not necessary for a lot of effort.

It is enough to unscrew the four screws on one side

And two on the other. This can be done using a regular crossbreed. Unscurately unscrew the screws and put it to the side. They may be needed when assembling. It is advisable to cover the table with a white cloth before disassembling, so that everything is visible, even the smallest details that may fall out during disassembly.


We start disassembly from the fuel supply system.

We remove the primer. a bubble of swing, which is noteworthy, when assembling, installing parts of the carburetor is simply impossible. Products have characteristic castings and holes.


Now remove the membrane. It is she who performs the function of pumping fuel to the carburetor.

With the vibration of the membrane, the other side exerts the pressure of the rocker of the mechanism and the needle rises, which, in turn, opens the hole and the fuel supply occurs.


Remove the carburetor lid with the injection mechanism.


Next, another membrane has been installed. We carefully remove it.


Under the membrane there is another gasket. We also carefully remove it, in no case damage.


Then we move on to the dismantling of parts from the back of the carburetor. As, earlier, we unscrew two bolts. This is already an air supply system.

There is a valve here, which, when the gas is added, opens and increases the air flow into the engine.

After its removal, the bare case remains in the hands. The carburetor is disassembled.

Determination of malfunctions and their elimination

Now it is worth paying attention to the problems that happen when the carburetor is operating and the methods of eliminating them.

Problem 1: Zaror of holes, channels and nozzles with mud

The first thing that happens is the holes and nozzles in the fuel supply system clogged with dirt. Filters installed in the tank and directly in the carburetor do not help. They still miss small particles, which cause motorcycles to fail.


To do this, unscrew the bolt on the mechanism, holding it with a finger. The fact is, there is a spring and a careless action will lead to the fact that it will be lost.


How to make a purge. The most effective way is the use of an ultrasound bath.

It is filled either with a special liquid or gasoline, a carburetor is placed there and under the influence of ultrasound, the so.called cavitation effect, the channels are cleaned from pollution.

The second cleaning option compressed air.

You can use the compressor available on the farm and clean the carburetor channels. However, this method is effective if the pollution is not very large.

If there is no ultrasonic bath or compressor at hand, then cleaning can be carried out in the third way using a special cylinder for cleaning the carburetor. They are sold in almost all car stores and supermarkets. The price is low and equals about 2-3, there is enough such a cylinder for 4 or 5 purges.

Step 0

Now we need to blow the channels in the case and the carburetor lid. See photo.

Step 1

Another particle of dirt can get stuck under the needle. Cm. a photo. This will also lead to the refusal of motorcycles.

Important! When cleaning the carburetor, in no case should not be used with needles, pins or wires. Even the slightest scratch will withdraw the carburetor from the system. It will have to be changed in its entirety.

Problem 2: Flaw clogging of thin cleaning

It is located on the cover of the carburetor and is a small metal mesh. Its pollution occurs very often. This is due to the precipitation of oil, additives, mud on it.

Step 2

Sometimes when disassembling the nets, a certain film is found. This carburetor lacks fuel and the lawn mower is either not starting or working with interruptions. The treatment methods are identical to the first reason: ultrasonic bath, compressor or spray can with a special solution. In addition, if the net is clogged thoroughly, you need to take a soft brush for watercolor paints, get wet into gasoline and rinse it carefully without damaging it.

Step 3

They have the ability to wear out during operation. From prolonged use, they are deformed, stretched, lose their elasticity, poor.quality fuel corrodes them, and can no longer perform their functions well. This also applies to the needle itself. The fact is that it is covered with a thin layer of rubber, which wear out during operation and can no longer enter the hole tightly. The lawn mower begins to work with interruptions. To eliminate such a breakdown, it is necessary to replace all worn parts. Where to get them?
