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.

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.

In what cases is it required to set the carburetor?

The stable work of the carburetor motorcosa largely depends on its correct setting.

The assembly adjustment is required in the following cases:

  • After the run.in a new trimmer for the grass, when 4–5 full fuel tanks were spent during operation;
  • with a frequent replacement by the operator of the brand used to refuel gasoline;
  • as a result of a sharp change in the weather;
  • due to long-term storage of a trimmer for grass;
  • as a result of arbitrary twisting of the adjusting bolts, motorcycles caused by strong vibration of its motor;
  • due to a sharp increase in the number of fuel trimmer consumed.

It will also be required to adjust the carburetor of the motorcycles in those cases when the soot quickly appears on the light of the instrument, as well as with a sharp increase in the volume of exhaust gases thrown out by the trimmer.

The main problems and malfunctions of the carburetor.

The grid has only two problems with this element:

To determine the cause of the malfunction, unscrew the fuel filter lid to remove the mesh filter. If dirt just accumulated on it, the washing of gasoline or purging will help.

Be sure to install a new filter if there are any visible damage. There may also be damage to the fuel line (check this item during the repair).

The starter of the carburetor in most cases does not work due to blockages. For washing use acetone or the same gasoline.

Filling the parts of the carburetor clogged air is an acceptable and convenient repair practice.

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.

Adjustment and repair of the carburetor of the lawn mower

The trimmer for grass does not apply to complex household appliances, so most of its breakdowns are mechanical and are quite successfully eliminated with their own hands. Even when the engine refuses for serious reasons. damage to the piston ring, for example, repairs are reduced to replacing the part.

But even with a relatively simple design, such a device as a carburetor needs to be adjusted.

Principle of operation

Carburetor. a module of the power system in which liquid fuel and air are mixed before supply to the engine cylinders. Depending on the tool and the mode of its operation, mixing and supply are regulated accordingly.

The device of the carburetor of the lawn mower is the same for almost all cases. It belongs to the category of float devices. The latter provide stable parameters of ready.made mixtures.

  • Air enters the body of a tube with an air damper. The latter enhances or reduces the air flow depending on its position.
  • On the site where a hole for supplying gasoline is formed, the tube has a narrowing. diffuser. Here the flow rate increases.
  • Fuel from the float chamber through the jet is supplied to the tube. The level of the float determines the amount of fuel supplied. Since the pressure is normal in the chamber, and in the tube is low due to greater air spare, gasoline is absorbed through the nozzle.
  • Accelerated air flow picks up the fuel and sprays it, forming the air-fuel mixture of the desired density.
  • The mixture is absorbed into the cylinder through the pipeline.

The stronger the air damper is open in the tube, the higher the density of the air flow, which means that more fuel enters the cylinder. The setting of the gas mowing carburetor is reduced to the installation of such a ratio of the damper, in which the density of the fuel mixture becomes optimal.

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:

The design of a benzotrimer carburetor and its purpose

Lawn mowers are equipped with internal combustion engines of a two.stroke type. To supply a fuel mixture to the engine cylinder, a carburetor is used. In the design of gasoline units is a key element without which ICE is impossible. over, this carburetor differs from the car device not only in size, but also by the principle of operation. In particular, this difference is the presence of a membrane that plays the role of a gasoline pump. It is due to the presence of a membrane that the devices considered in the design of two.stroke internal combustion engines are called membrane.

Structurally, the entire mechanism is a small part, inside which there are channels, valves and membranes. The carburetor case is made of aluminum, and the internal device is shown in the photo below.

Before adjusting the carburetor of the lawn mower with your own hands, it is necessary to deal with all the constituent elements of the device in question. The carburetor of the lawn mower and a trimmer for the grass consists of the following details:

  • Venturi diffuser or nozzle. through this nozzle, air is absorbed into the system
  • Air damper. opens and closes the feed of filtered air
  • Fuel channel maximum revolutions
  • Fuel channels (nozzles) of the idle speed of xx and medium revolutions
  • Throttle. the opening value is regulated by pressing the gas
  • The fitting of the pulse channel. connects to the internal channel of the engine crankcase
  • Inlet fuel channel (fitting) (2). the supply of fuel from the gas tank is ensured
  • Membrane (4). is responsible for absorption of fuel from the gas tank
  • Fuel absorption valve from the tank (3)
  • Fuel supply valve to the carburetor channel (5)
  • Filtering element (6) or filter of fine fuel cleaning
  • Fuel channel (10)
  • The needle of the needle valve (14) is responsible for supplying fuel to the chamber of the control membrane
  • Camera. fuel mixture, which is supplied through nozzles and throttle ditch into the cylinder
  • The control membrane (18). is ensured by the manual fuel sucker primer
  • Lever connected to the membrane (17)
  • Idle adjustment screw (15)
  • The adjustment screw for the amount of fuel supplied to the diffuser (13)

Having an idea of ​​how a carburetor is arranged inside, you have to deal with the principle of its work. A detailed description of how the carburetor works on a two.stroke internal combustion engine on the example of a chainsaw is described in this material.

How the gas mowing carburetor works or the principle of functioning

The adjustment of the carburetor of the Chinese lawn mower is completely identical with the setting of travokosylovs of European, and manufacturers. To cope with the task of adjusting the carburetor on benzocos and benzotrimers, you need to understand the principle of their functioning. How the carburetor works on a benzos, step.by.step and available described below.

  • The operation of the carburetor of the lawn mower begins with the supply of fuel through the channel, as shown in the diagram
  • The absorption of fuel into the carburetor occurs using a pulse channel connected to the engine card. Due to the vacuum of air, a flexible membrane is moved under the number 4 in the diagram above
  • Through valves 3 and 5, fuel supply occurs. The valve 3 is inlet, due to which the fuel is supplied to the sub.sector, and the valve 5. the exhaust
  • Further, the fuel moves through the channel and, passing the filter of thin cleaning, reaches the needle valve 14
  • The needle valve is connected by means of a lever with the control membrane 18
  • The needle valve is driven when exposed to the membrane. When it is necessary to pump up the fuel to start the engine, it is necessary to affect the soft cover of the manual pump. When exposed, the needle is opened, and the camera is filled with the fuel mixture
  • Когда же двигатель запускается (на холодную), то открытие иглы происходит за счет разрежения при закрытой воздушной заслонке. This vacuum affects the nozzle nozzles and high speeds on the membrane 18
  • The membrane acts through the lever on the needle valve, through which the camera is filled
  • After starting the motor, the air damper opens, as a result of which the engine operates on the depleted mixture, since the fuel is mixed with air
  • The fuel mixture with a filled chamber is supplied (sucked) through the nozzle jetlays and medium revolutions (when the engine is launched)
  • The throttle shift at the same time shifts from the original position by 10-15 degrees
  • When the work is carried out under load, then the fuel begins to enter the chamber through a nozzle nozzle, and at the same time the throttle shift turns to an angle up to 90 degrees (depends on the force of pressing for gas). In all operating modes, an air damper should be open, through which the fuel is mixed with air, and thereby there is an ignition of the mixture in the cylinder

The following shows the principle of operation of the carburetor of the lawn mower. Based on the scheme, you can not only deal with the principle of operation, but also identify breakdowns and other malfunctions of the mechanism.

When operating the tool, it is necessary to take into account the presence of another nozzle. This nozzle is located between the channels of the idle and full power. It is necessary in order to exclude a strong impoverishment of the mixture, which occurs in the case of the engine at an incomplete load. In such a situation, the occurrence of a back of a pair is not excluded. Through the additional channel (nozzle), fuel is sucked into the chamber, through which the fuel-air mixture is enriched. Below is an additional nozzle, which is indicated by the number 1.

Having an idea of ​​the design of the membrane carburetor of Motokosa and the principle of work, it will not be difficult to configure it with your own hands. To adjust the carburetor of the lawn mower, adjusting screws are used. The scheme above shows two screws for configuration, but most modern models of gasoline trimmers are equipped with three screws. The presence of three setting screws allows you to perform a more accurate adjustment, while achieving stable and uninterrupted operation of the internal combustion engine.

Summing up

First you need to carry out maintenance. clean the candle from the cargo, adjust the gap to adjust. Then you need to remove and clean the air filter from dust and dirt.

Next, it is necessary to adjust the idle stroke. so that the air damper opens almost completely, leaving a small free stroke of the cable.

After that, install the candle and the filter back, and we are already adjusting the supply of gasoline supply and idle screw for the supply screw.

information on how the adjustment and maintenance of the carburetor Motokosa is performed can be viewed in the video below. The review was prepared on the basis of the author’s video from the YouTube channel “Border 13”.

How to adjust the carburetor of the lawn mower with your own hands

Adjustment

  • Run the motor. When it is launched on the XX, knives should not rotate, but if the opposite occurs, then we reduce the speed of the idle.
  • We adjust the screw l. He is responsible for the mixture at low speeds. First, scroll to the stop clockwise, then unscrewed 90 degrees against the sentry. If you find failures, we repeat this action, weakening it for 1/8 part, that is, 45 degrees.
  • Adjust the La screw, more frequent name. t. With an increase in speed XX, more air is added to the mixture. Power is lost. But if there is not enough air, fuel is burned worse. We unscrew the screw so that it works perfectly at low speeds, while the knives should not rotate. In the process of setting, you need to feel momentum, it should work stably on XX.
  • Adjust the screw h, which sets up the mixture at high speeds. To identify their maximum quantity, we use a tachometer. Upon reaching the largest number of engine speed, we unscrew the screw to the left by 180 degrees, the adjustment on this ended.

How to find out that the gas mowing carburetor needs to be adjusted

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:

carburetor, motokosa, tachometer, lawn, mower
  • After passing the running.in. 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.

The device of the carburetor of the lawn mower

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.

The principle of operation of the carburetor of the lawn mower

The throttle dashes determines the amount of air for supply, and the engine power directly depends on this.

Fuel is sucked into the carburetor system (its membrane). Then passes through the fitting in the carburetor. Next, the liquid moves through the intake and exhaust valve of the pump. Filtered with a net. The needle valve moves into the membrane chamber.

  • Air supply to the tube with an air septum (damper). The partition regulates the intensity of the air flow.
  • The fuel supply system is necessarily narrowed by a diffuser to increase the flow rate.
  • Gasoline through the float chamber and nozzle with narrowing. The chamber with a float regulates the temporary volume of gasoline. In the float chamber, the pressure level is neutral, and in the tube with narrowing is already low. Thanks to the pressure drop, fuel penetrates through the jetler.
  • Air flow acceleration contributes to the transfer of fuel (gasoline) and its spray. As a result, the air-fuel mixture of the necessary proportion or density is formed.
  • The air-fuel mixture penetrates the engine cylinder through the fuel tube.

The level of air density in the system depends on the area of ​​the open air damper. The wider the damper is, the greater the fuel consumption and power.

Simply put, adjusting the carburetor on a benzocos. creating an optimal fuel mixture due to the correct air supply.

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 shut.off 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).

Step.by.step 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.

Step

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.

Step

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.

Step

Remove the carburetor lid with the injection mechanism.

Step

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

Step

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

Step

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.

Step

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.

Step

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?
