Carburetor of the chainsaw

Carburetor of the chainsaw.This is an element that is responsible for mixing the air fuel mixture. Not only the stability of the engine, but also the speed of the entire chainsaw depends on the state and serviceability of this important node. In this regard, each owner of the garden tool must study the design of the carburetor, as well as get acquainted with the rules for its maintenance and repair.

Most modern chainsaws are equipped with almost the same carburetors. They are practically no different from each other, and work according to a similar principle. The only difference between cameras of different manufacturers is the material from which they are made. In expensive chainsaws of American, Swedish and German production, the cameras are made of reliable alloys on which protective coatings are applied. Cheap Chinese and Korean chainsaws are equipped with knots made of cheap materials.

Each carburetor consists of the following elements:

  • Aluminum body with a whole structure. Inside the housing is the input fitting, the main screw, the pulse canal, the engine for adjusting the engine when working at idle;
  • Throttle. It is responsible for adjusting the amount of air required to enrich the fuel mixture;
  • Diffuser. Located next to the input hole of the camera;
  • Sprayer. Designed to feed the fuel mixture directly into the carburetor chamber;
  • Float chamber. There is a float in it, which works in the case of an insufficient amount of fuel;
  • Jetlars. Are valves that are responsible for adjusting the amount of fuel.

This diagram of the chainsaw carburetor is as simple and effective as possible. In some models of garden tools, it can be supplemented with additional pipes, oil seals or filters.

The principle of operation is a chainsaw carburetor is quite simple. At the time of starting the engine, the air damper opens, located at the bottom of the case. In this case, a vacuum caused by the piston movement is formed in the float and air chambers. As a result, a regular diffuser is triggered, which begins to absorb air. The amount of air taken depends on the degree of opening of the damper. When the piston is triggered, the fuel begins to enter the chamber through the input fitting. Its number and rate of flow depend on the position of the jetgles.

Subsequently, fuel in the air chamber begins to mix with air. After that, the finished air-fuel mixture passes through the inlet valves, from where it is directed into the combustion chamber of the engine engine.

How to set up a carburetor of a chainsaw Shtil 180?

Only idle adjustment is available to us. Why is it necessary and how to understand when you need to configure idle speeds not a chainsaw of Shtil 180? This is necessary if the chain does not stop at idle, which can lead to injuries, unstable operation of the saw in general.

The procedure for adjusting the STIHL MS 180 carburetor:

In the instructions for MS 180 it is described how to standardly configure idle on a chainsaw:

We turn the blanket of the idle speed against the sentry until it does not go tight, then we turn it off for two clockwork clockwork. How to remove magneto from a chainsaw, video, watch. Voila! Tun

If your saw has too low idle speeds, then we carry out the following actions:

If you have high speeds and the chain does not stop spinning:

  • We turn adjustment screw Military speed counter-clockwise the arrows until the chain does not stop moving.
  • We rotate the screw even on a hollow against the sentry.

If you fail to independently adjust the speed idle move, then you need to contact a specialized service center.

Here you can read about the adjustment of the carburetor Khuskvarna:

Accurate settings of the chainsaw

The accurate adjustment that the Urals Carburetor is subjected to is carried out only in a preheated state, preferably by specialists who have the right equipment. The procedure for setting screws is as follows: first the screw l, then h and at the end of the idle screw t.

First, the largest speed at idle is determined. To do this, the screw l is slowly rotated and after the position of the largest revolutions is found, the screw rotates ¼ turn against the course of the clock.

The screw h affects the power and frequency of speeds that the carburetor of the chainsaw of the rosary. You need to warm up the engine at full speed of 10 seconds, turn the screw for ¼ turn against the course of the clock. Let the engine work, and then check the maximum speed with a tachometer.

The exact adjustment of the screw T is carried out with the engine operating, the screw rotates clockwise until the saw chain begins to rotate. After that, the screw t should be twisted in the opposite direction until the chain stops.

To adjust the Husqvarna chainships, it is best to contact a specialist who can correctly configure all the necessary parameters to the tachometer.

How to rinse a gasopyle carburetor?

To clean the node from strong contaminants, it is best to use a tool that is delivered on sale in cylinders under pressure. Included with the cleaner, there is a dispenser and a long thin tube, which makes it possible to spray the product in any inaccessible places.

It must be remembered that cleaning the carburetor on the chainsaw is performed using flammable chemicals. You need to work with them in a special protective mask and only in well.Ventilated rooms.

To clean the carburetor on the chainsaw, the knot will need to be partially disassembled. Throttle, adjusting screws, housing and other parts of the carburetor will need to be washed with a core with a cylinder and postponed until completely dry. As soon as all the elements dry, the node can be assembled and installed back on the chainsaw.

Gasoline does not enter the carburetor of the chainsaw

If the fuel does not enter the standard camera, then this can talk about several breakdowns at once. First of all, you will need to check the air and fuel filter. With prolonged operation of the saw, these elements absorb a large amount of dust, which further prevents the sewing of clean air and fuel. The weakly pinched filter can be cleaned with gasoline, but if the part is clogged with a lot of dust, then it will need to be replaced.

Another cause of the malfunction is the needle. This detail is characterized by sticking, especially in a chinese.Made chainsaw. To eliminate the malfunction, in most cases it will be quite simple to move the needle.

If the fuel does not enter the chamber, then the owner of the saw should examine the tools of the tool. After several months of using the tool, these parts lose their tightness. Over time, they begin to skip gasoline, as a result of which the tool ceases to start. Repair is carried out by replacing the oil seals.

When starting a saw, an important role is played by a sapun. It is near the saw cover cover, and performs 2 tasks at once. It maintains optimal air pressure, and does not allow me to flow out. To check the saapun, you will need to turn off the pipe for supplying fuel and see how intensely the gasoline flows out. If it does not follow at all, then the full.Time sapun is clogged with garbage and dirt. In this case, you will need to clean the element and install it in place.

If the fuel does not enter the camera, then you need to check the fuel highway. Most often, a Chinese hose is used to equip the budget class tool, which eventually loses its tightness. In this case, you will need to replace the highway, paying special attention to the tightness of the joints of the channel.

Carburetor. How and how to clean a carburetor?

Instructions for your car. It is needed to remove, disassemble, assemble and install the carburetor again. Clean smooth rags, not terry. Carburetor cleaner (spray and liquid). Long rubber gloves resistant to strong solvents. Cleaned air spray. Glass or metal jar, which will not dissolve when contacting with the solvent. Sticks or toothpicks. Protective glasses (according to safety precautions). Old clothes that are not a pity to spoil. Wrench and screwdrivers. There is a large selection of cleaners for carburetors. They are produced by many automobile and chemical companies. Go to the car shop and select any cleaner specifically for cleaning carburetors. If you are offered another, not a specialized cleaner that solves organic fats well, refuse. He may well clean his pants or electric stove in the kitchen, but may not cope with dirt in the carburetor. Before starting work, be sure to read the instructions for the use of carburetor cleaners. They usually contain powerful organic solvents, are easily ignited and toxic. They should be used only in a well.Ventilated room. They are also aggressive in relation to paints, plastic lenses of your glasses and fats of organic origin, so be careful. If you thought it was enough to spray with a spray in a carburetor, and everything is ready, then we hasten to disappoint you. This will not help. A strongly contaminated carburetor will have to remove, disassemble and clean all its components. To remove and disassemble the carburetor, follow the instructions for the repair of your car. Make sure not to lose springs, screws and other small details. Disassemble the carburetor, clean every detail. All rubber and plastic parts should be isolated from the cleaner, as it can deform them. After you disassemble the carburetor, collect metal parts in a metal box or glass jar and pour them with a cleaner and let stand, periodically mixing. Then, under a stream of water, clean the parts with an old toothbrush or toothpicks. Do not try to pick on the weekends in the carburetor and valves. These holes serve fuel and air and are very important for the coordinated operation of the engine. Such holes are cleaned with aerosol or compressed air. Liquid cleaner can be used again. Some economical motorists use the cleaner several times. After completing the carburetor cleaning, dry it thoroughly and collect it according to the instructions. The cleaned carburetor will need to be installed in the car and adjust it again. To prevent carburetor pollution, it is necessary to change air and fuel filters in time. This must be done every time you change candles.

How to clean a carburetor on a chainsaw?

Washed a gasopyle carburetor or clean it only when it is removed and disassembled. Before cleaning, you need to prepare everything you need in advance: two screwdrivers (plus and minus), lacture keys, but better the head with nozzles, clean rags, a special cleaning agent, pump and ultrasonic cleaner (recommended). Before proceeding with cleaning, you need to drain all gasoline. This is necessarily. After the remaining fuel is merged and the entire tool is prepared, we proceed to cleaning:

  • Disconnect the top cover and remove it.
  • Gently remove the fuel pump membrane.
  • There are spring brackets on the left side of the case. After they are disconnected, you can see the screws under the brackets. They also need to be twisted.
  • Unscrew the lower cover.
  • Having unscrewed the screw, get access to the needle valve. Its and the spring located under it must be carefully removed, so that you do not lie down the needle.
  • The air damper is dismantled with a slight longitudinal force, after which the axis is removed.
  • Lastly, the throttle, lever and axis removes.

After the carburetor is disassembled, all parts must be laid out on a flat surface on a clean rags. Carefully inspect each detail for clogging or wear. Pay special attention to the giklers and inlet fitting. Their clogging is the main reason why gasoline does not enter the carburetor of the chainsaw.

If for some details it is clear that it is very worn out, it is better to immediately replace it with a new one, so that in the future not to think again how to repair a chainsaw carburetor.

Do.It.Yourself carburetor carburetor is cleaned using a special detergent. It is necessary to rinse every detail well, and then dry them with a rag of biased fabric, and preferably compressed air. All channels are also blown by air.

If there is an ultrasonic cleaner at hand, then this is even better. Pour diesel fuel into the bath, put carefully polluted parts there for 5-10 minutes and after cleaning, dry them with compressed air.

How to ultrasonic clean a carburetor

Assembly is carried out in the reverse order. A very important point is the installation of a needle valve. It should rotate freely in the planting nest. If the petal wedges, press it slightly or press it to sit deeper.

After cleaning, it is strongly recommended to wait 20-24 hours-this is necessary so that the cleaning agent completely evaporates. Otherwise, it is mixed with the fuel mixture and will fall into the cylinder, leaving the carpet on the walls after combustion.

Cleaning the carburetor of the chainsaw and how to do it correctly

When operating the unit, dust, small stones and other pollutions often get into its fuel tank. The fuel filter is responsible for their capture, but with frequent operation of the chainsaw, the filter is gradually polluted. As a result, he loses the ability to fulfill his function.

This element can also be subjected to such a negative process as oxidation. Deposition of oxide on the inner walls of the fuel tank. This happens if for a long time the chainsaws were not operated, and fuel remains in its tank. After that, the start of work leads to the sediment entering the carburetor, clogging it.

How the chainsaw carburetor works. Features of air flow

The principle of operation of the carburetor of the chainsaw also includes the supply of the air mixture to the device. As you know, not pure fuel (oil with gasoline) enters the combustion chamber, but the fuel mixture is oil with gasoline from the tank and air, which previously passes through the filter element.

It is interesting!The filter that is installed on the carburetor must be regularly cleaned, otherwise its clogging helps to reduce the flow of air into the system, which often causes improper operation of the unit. Many inexperienced sawmen are immediately accepted for setting up the carburetor, however, it is enough to clean the filter and blow it up with a compressor to eliminate the causes of uneven or unstable operation of the tool. So, the air passes through the filter, and enters the device through the membrane under number 7.

Air damper 7 during cold starting is almost completely closed, as shown in the diagram. Through it there is a slight flow of air into the system. Air enters the diffuser 16. Number 12 indicate channels or nozzle nozzles and medium speeds. These channels are interdependent, that is, the average speed channel is transitional from the idle. These channels are constantly open, so the fuel in the corresponding dosage enters the diffuser, where it mixes with air, heading for the cylinder.

Under number 15, the maximum speed channel is indicated, which consists of a valve with a rubber base. Through this valve, fuel is supplying in one direction. Into the camera of the diffuser. Next, the throttle 8 enters the system, the movement of which depends on the force of pressing the gas gas on the gas. When starting the valve 8 vertical position, so the chainsaw works only on the fuel mixture coming from the xx channel. The amount of air is small, since the damper 7 is also open by several millimeters. When pressing the trigger of the instrument, the damper is deviated by 10-15 degrees, as a result of which the fuel mixture from the medium-speed channel 12 on the diagram above is supplied.

When the saw begins to saw wood, then the number of revolutions increases to maximum, so the damper moves to an angle of up to 90 degrees from the original position. An increase in the amount of fuel occurs, which helps to accelerate the burning of the fuel mixture.

To fill the chamber with a 14.Fuel mixture of gasoline with butter, which enters the channel closed with a needle, you need to create a vacuum, due to which the membrane 13 will be pulled inside, thereby acting on the stem. The vacuum in chamber 14 is created while pulling the starter handle when the crankshaft moves the tool. The piston moves up and down when “shhrings” or “poked” the starter handle, which provokes the creation of pressure inside the camera 14. As a result, the camera is filled with fuel, which enters the corresponding channels to the diffuser, mixing with air, and heading for the cylinder.

After the unit engine is launched, the piston will begin to move under the influence of the burning mixture, so the vacuum in the chamber is formed constantly, which actually provokes the bending of the plate 13, which affects the needle valve through which fuel enters the main chamber of the carburetor of the tanker.

Actually, this is the principle of operation of the carburetor of the chainsaw of the membrane type, the functioning of which does not depend on the angle of its location. Knowing the design and principle of operation of the unit, you can begin to set it up, cleaning and adjusting it.

How to adjust the carburetor on a chainsaw correctly?

Before you configure the carburetor on the chainsaw, you need to carefully prepare for the procedure. First of all, it is necessary to find the description of the rotation angles of the adjustment screws in the operating manual for the operation. If you arbitrarily turn the bolts without adhering to the instructions of the manufacturer, this can lead to a serious breakdown of the ICE of the tool.

The motor itself should be in a completely good condition. Before setting, you also need to carefully clean the air filter. Otherwise, he will not be able to pass the air in the volume required to enrich the fuel mixture, which will lead to improper tuning the carburetor.

The control of the node should be performed on a flat surface. The saw itself should be installed in such a way that its saw headset is located away from the legs and face of the operator. Immediately before setting, you will need to remove the upper part of the protective plastic body of the tool, as well as extract foam rubber and part of the standard air filter. A thin figure screwdriver is required to perform the assembly of the node.

You need to adjust the gasopyle carburetor in 2 stages. The first of them is the base. During its execution on the turned off the chainsaw with a cold engine, you must alternately screw the b and l bolts in the direction of the watch arrow until the clock. After that, each of the screws will need to twist them for 1.5 turns in the opposite direction.

The final tuning of the carburetor is performed in the following order:

  • First, you need to start a chainsaw and give it time to fully heating the engine. In this case, the gas lever should remain in the position of average revolutions;
  • Further, the screw responsible for the idle revolutions of the motor will need to slowly turn the clock along the hand. This must be done until the ICE of the saw becomes stably;
  • If during the stable operation of the motor the chain moves along the tire, then the same bolt needs to be slightly twisted in the direction against the watch arrow;
  • Then you need to connect a manual tachometer to the motor. With it, you need to find high and low ICE works. To do this, the adjusting bolts H and L need to be turned alternately in different directions until the devices are indicators indicated in the instructions for operating instructions.

At the end, the chainsaw used will need to be drowned out and start again. It should work stably at idle, and its chain in this mode should not rotate along the tire. When pressing the gas trigger, the saw should quickly gain momentum, and when releasing it, to discard them.

Malfunctions and their elimination

Do.It.Yourself carburetor repair of a chainsaw allows you to eliminate all the malfunctions that appeared during the operation of the device.

If the internal combustion engine is spinning with interruptions and accelerates the course for a long time, then you need to twist L against the sentry at 1/8 turnover. Then set the bolt s. The settings should be made until the engine begins to function correctly and quickly accelerate.

Then check the adjustment of the screw h h. Accelerate the motor to maximum. Watch the exhaust and how the motor is spinning. If bluish smoke comes from it and a saw loudly rustles, then this means that the carburetor creates a too rich mixture. The highest speed ICE is less than the norm. Nar is formed in it. With such a problem, you need to scroll a bit clockwork slightly. Then they control the operation of the motor and, if necessary, repeat the setting.

If the saw screens, this means that the engine overheats, the exhaust occurs with a bang, interruptions are observed during ignition. This means that the mixture is unsaturated, and the largest revolutions of the motor are greater than the norm. This leads to overheating of the motor, combustion of the piston, cylinder and the burning of the candle. If such a problem occurs for configuration, it should be turned H to 1/4 turnover against the movement of the watch arrow.

If there is no fuel in the combustion chamber, such a malfunction is caused by a clog of a filter for fuel, nozzles or channels of the device. To eliminate the malfunction, a complete disassembly of the filter and purging these channels using the compressor will be fully disassembled. For cleaning channels, use a liquid for a carburetor.

It happens that in a carburetor there is a fuel overflow. This turns out if the membrane has failed, dried up and boiled, began to put pressure on the rocker attached to the needle. Then the needle is regulated. To change the membrane, you need to remove the carburetor.

The motor works with interruptions, does not gain speed of rotation poorly. This happens when filter clogged. It is necessary to remove the device cover and clean it using detergents.

How to remove a carburetor

Before repairing or cleaning the carburetor, it must be dismantled and disconnected from other systems. The dismantling of the carburetor is carried out as follows:

  • Remove the top cover. To do this, unscrew the bolts (3 pieces), which are located around the perimeter of the lid.
  • Remove the carburetor filter.
  • Then turn off the gasoline supply hose.
  • Disable the traction of the motor drive.
  • Take the tank connection tip.
  • Carefully remove and pull out a gasoline supply hose.

Disassembled with your own hands

Dismantling the carburetor of the chainsaw of the chomelite is as follows. Prepare a place. Flat surface. The following tools will be needed:

After you dismantled the carburetor, you should disassemble it. Dismantling the carburetor is carried out in the order, which is provided by the design of the device.

After disassembly, the device is defected and non.Working parts and nodes are replaced. Rinse the device with a special liquid, dried, wiped with a dry cloth. Blown with compressed air tubes and nozzles. Before that they are processed with ultrasound to eliminate the plaque.

How to clean

When conducting work with your own hands, you need to roughly know how the carburetor is cleaned and washed. Rinse the device as follows:

  • Unscrew the screws on the device case.
  • Open the lid, pull out small parts and lay them on fabric.
  • Process the walls of the device and all parts with air from the compressor.
  • If the naggers remained on the nodes, then they are wiped with a degreaser.
  • Nodes and housing are dried.
  • Collect all the nodes of the carburetor and install it on the chainsaw.

It is necessary to rinse the carburetor if low.Quality gasoline was used to refuel it or used a chainsaw in severe frost. After cleaning, the engine will work better, and the chainsaws will spin faster.

1) STIHL MS 180 chainsaw malfunctions: Gas wedge wedges and, finally, the gas key completely stops moving. Cause: Transparent translucent resin on the throttle shaft of the carburetor, which leads to the capture of the throttle. The resin is formed when gasoline dissolves a defective coating of the air damper. Chainsaw repair: The axis of the throttle of the throttle of the carburetor should be cleaned with acetone, and the air damper itself should be peeled by tin.

How to clean the carburetor of a chainsaw with your own hands. Instructions with a step.By.Step description

A common situation when a chainsaw is revealed during the repair of a chainsaw that the cause of problems is a carburetor. Often the malfunction of this device is to clog channels. The constituent elements of the mechanism that can be replaced by performing the corresponding repair can also fail. Next, find out how you can clean the chainsaw carburetor yourself without the use of an ultrasound bath. To carry out the procedure, you will need to buy a special cleaner for the carburetor CarbCleaner. In extreme cases, you can use the WD-40 solvent, however, the difference between these substances is very large, and for greater effectiveness it is recommended to give preference to carbclineer.

It is interesting! If you do not know how to rinse the carburetor at home, then it is definitely worth choosing a special carburetor cleaner. A small jar of liquid is enough for a chainsaw device.

There are no difficulties with the dismantling of the carburetor of the chainsaw, so then a detailed instruction, how to clean the device with your own hands:

  • Dismantling should start from the location of the membrane pump, from where the fuel mixture is pumped. To do this, the fastener is unscrewed with a screwdriver
  • The upper cover is removed, under which there is a membrane playing the role of the fuel pump
  • Immediately you can evaluate the state of the membrane, which should be soft and elastic. If it has become stiff and rude, then it should be replaced
  • After that, evaluate the condition of the filter mesh. In most cases, it will have clogs that prevent fuel intake in the fuel chamber of the carburetor. On the example of the mesh, it has significant contaminants that should be removed. To do this, the filter element is dismantled, which must be done in any case, since this channel will be cleared
  • After that, we proceed to disassemble the back of the mechanism. To do this, you should twist 4 fasteners with which the plate is fixed
  • After removing the plate, we have another membrane that controls the needle
  • This gasket due to air vacuum controls the needle, ensuring its opening and closing for the receipt of the next portion of the fuel mixture. The membrane should be soft and elastic, otherwise, it should be replaced
  • Check the serviceability of the foot that connects to the needle. If the paw has a small move (concave inside), then it should be bent for 1 mm to itself. The small stroke of the paw limits the possibility of opening the needle to complete, which affects the reduction of engine power, and also leads to the impossibility of developing maximum speed
  • To bend the foot, as well as to clean the carburetor, you will need to unscrew the fixing screw. And dismantle the part with the needle
  • After weakening the screw fastening, remove the foot with a needle, which are fixed with a spring
  • At the next stage, the adjusting screws should be unscrewed. It is very important to remember their location, as they have a distinctive design. For this, it is recommended to mark them with a marker. You do not need to twist the idle adjustment bolt
  • After that, you can start cleaning the device. It should be understood that the devices of carburetors may vary slightly, but the principle for everyone is practically identical
  • To clean manually, a special cleaner with a thin pipe on a spray is used
  • Work with the cleaner must be performed in special goggles, as well as oil.Bonas.Resistant gloves. This is very important, since the cliner is an acid that corrodes the skin. The clinker needs to clean the carburetor, for which a stream of solvent is supplied to the holes
  • The channels of high and low revolutions are also being cleaned, from where the adjusting screws were unscrewed
  • Similarly, the channels are purged on the other side of the carburetor
  • The cleaning process will not be effective if you do not purge the idle channels, low and high speeds. To do this, the throttle is opened, and access to these channels that should be blown to blow out
  • If these channels are oxidized, then the cliner may not help in cleaning them, so it is possible that an ultrasound bath will be needed
  • After washing the mechanism, you should make channels purge. This must be done carefully, holding a purge gun at the corresponding distance of 5 cm
  • Next, the device is assembled. The filter mesh must be cleaned, produced and installed in place
  • When installing the needle, you should also carefully clean it from oxides using the wedger
  • Adjusting screws must also be cleaned with the cliner, after which we screw them in place. They need to be screwed until it stops, and then weaken at 1.25-1.5 turns

Detailed describes how the chainsaw carburetor is regulated, presented in the video.

The malfunction of the circuit carburetor

Remove the carburetor from the chainsaw. Remove the gas pump lid using the diaphragm, unscrewing one screw in the center of the lid. Then turn the carburetor to yourself with the help of a throttle, from the side where there are two holes, in one pin is visible, here there is an accelerating pump under it. Remove the locking ring with the outer side of the pin and disconnect the air damper of the wire spring. Unscrew the screw in the center of the throttle, remember how the throttle is installed (and then put it) and remove the throttle. A hole for a finger pin (the accelerator is springy, and if you pull out the shaft of the throttle and do not close the hole, then the accelerator will pop up), then turn the shaft of the throttle and remove it. Shake the accelerator (piston) with a spring from the hole. There is a rubber cuff (ring) on ​​the piston. Its wear is the cause of the chainsaw malfunction. It is necessary to replace the piston with a rubber cuff and a spring (they are sold as a repair kit). Or you can remove a worn piston with a spring and plug the hole, scoring a rubber plug (the chainsaw will be without an accelerating pump, t. E. It will not accelerate for 3 seconds, but for 4 seconds, but it will work well because there will be no carburetor absorption).

Assembly after repairing a malfunction of the chainsaw (after removing the malfunction of the carburetor chain saw) is performed in the reverse sequence of disassembly. When assembling the throttle, before screwing the screw, the throttle should be correctly located so that it does not stick, and screw the throttle shaft on the axis, degrease and lay out with a special sealant for thread (sold in small pipes, red, liquid) or pliers, because, because, because, because, because, because If this bolt comes out during operation, it goes directly to the cylinder), and the repair or replacement of the piston cannot be avoided). Therefore, we examined the elimination of this malfunction of the chainsaw.
