Benzotrommer carburetor does not pump gasoline. Recommendations for storage of gasoline trimmers per season

trimmer for stihl grass does not work fuel pumping

Often, with the onset of spring, most owners of benzos complain about the inability to launch the motor of this grass.shocked tool. With what it can be connected? So that the trimmer for grass in the spring after winter storage is well started, you must learn to care for it correctly. How to properly store the lawn mower in winter is described in detail at the very end of the material. Now we will figure out why it is impossible to start the tool engine after winter.

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

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

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

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

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

STIHL chainsaw stalls. does not develop momentum

All STIHL chainsaw systems function well, ensuring the launch of the mechanism. But sometimes, with confident work of idle, the saw does not gain revolutions at the load, interruptions begin in the motor. This means that there may be serious reasons requiring repair: to unbalance the carburetor screws, the end of the engine resource, breakdown of the candle or ignition coil, wear of the piston group.

But, most often, the engine does not develop turns, or may stall, when the check valve is out of order, a vacuum is created, which causes malfunctions. To repair the valve quite time.consuming, so it is better and faster to replace the oil tank cover, its cost is quite affordable.

Features of diagnosis

Trammers for grass can be attributed from a technical point of view to complex devices. Based on this, before their operation, it is strongly recommended to carefully study the relevant instruction. However, in practice, many ignore it, often then find themselves in situations where the gasoline trimmer for the grass does not start or is poorly gaining momentum in the process. It is worth noting that you can encounter such problems by purchasing new samples of technology.

One of the most common causes of such symptoms is a long seasonal break in the operation of equipment. In addition, poor.quality and untimely maintenance can lead to extremely negative consequences. It is important to remember that this is relevant for both the Chinese lawn mower and the representatives of the model rows of eminent brands.

The key to effective and operational repair will, of course, be competent diagnostics of the device. In the process of identifying malfunctions, you will have to inspect and test, first of all, key elements. The list of such includes candles, tank, filter nodes and valves of the fuel system. As practice shows, very often the malfunctions of these elements become the reason that the lawn mower does not start. The quality and correctness of the preparation of the fuel mixture deserves special attention, especially when it comes to two.stroke engines. In relation to this parameter, the manufacturer’s recommendations should be clearly followed in order to avoid serious breakdowns and expensive repair work. In the case of, for example, with the Piston Group of ICE, expenses are able to amount to 70 percent of the cost of new equipment.

Often, the owners of the trimmers have to deal with situations when the indicated mixture is high.quality, the carburetor is serviceable and configured, and the device still does not show signs of life when trying to start the engine. In such cases, the condition of the candle should be checked. The following steps will allow to eliminate the problem:

• turn out the candle;
• wipe and dry the part (pumping is undesirable);
• remove fuel and dry the candle channel for 30–40 minutes; Such actions will avoid filling the candle with another attempt to launch;
• completely eliminate the traces of soot using a file or sandpaper;
• set the appropriate gap;
• put the candle in place.

If the candle turned out to be the working and the planting nest is completely dry, and the engine of the braid for the grass is not started, then the thread should be moistened with gasoline. It is worth remembering that regardless of the quality of the issued spark, initially in a completely dry chamber, there will simply be nothing to ignite. Faced with the fact that the spark does not act, it is worth paying attention to checking the contact between high.voltage wiring and candles. If this connection is of high quality, then it will be necessary to check the performance of the ignition control unit unit. In such cases, a qualified specialist is unlikely to do without services.

The next stage in the diagnosis of gasoline braid for grass will be checking the state of filters. Often, the lawn mower is poorly started or does not start at all on the cold due to the fact that the air filter is clogged. This malfunction can be identified by excluding it from the system. If after that the braid for the grass starts, then you will have to clean or change this element. Experienced users strongly recommend periodically blowing an air filter to maximize its operation.

The described tool can also not be started due to problems with the supply of gasoline provoked by fuel filter pollution. For the quick and efficient elimination of such a breakdown, you just need to replace the filter element with a new. It is important to remember that the suction pipe must be equipped with a filter, which is provided for by all instructions. Non.compliance with these rules and recommendations may entail expensive piston repair. In the process of diagnosing and searching for source of problems with the launch of a mower, attention should be paid to the saapun responsible for stabilizing the leveling of pressure in the fuel tank. In addition, it is necessary to check the cleanliness of the exhaust channel and muffler grid. As a rule, such problems are most often encountered during the defect of old models.

Main reasons

As practice shows, gasoline trimmers for grass cease to start or function normally after winter, that is, long.term seasonal storage. Before subsequent attempts to launch the tool, a thorough diagnosis should be carried out in order to determine the source of problems. There are currently several of the most common causes of malfunction.

• Initially, it is necessary to check the quality of the fuel. Savings in such cases may have extremely negative consequences. Experienced owners of Motokos and experts advise preparing a mixture, the volume of which will correspond to the upcoming work, since its surpluses quickly lose their qualities.
• Trammers for grass of such eminent brands, such as, for example, Husgvarna, Makita, Stihl, are very sensitive to the fuel used. We are talking about fuel quality and octane number. Ensure suitable operating conditions and extend the life of the equipment will allow the refueling with high.quality gasoline.
• At the time of the launch of an internal combustion engine, the lawn mower can stall due to the fact that it floods the spark plug. Often in such situations you have to deal with the need to configure the carburetor. It is worth noting that similar problems arise when a braid for grass stops starting on a hot.
• Sometimes the tool cannot be launched, although the candle is wet, which in turn indicates the intake of the fuel mixture into the combustion chamber. As a rule, this is one of the symptoms that there is no spark. The reasons may be the absence of normal contact between candles and a high.voltage wire or drying out the threaded connection in the candle channel.
• If there are no problems with a spark, and at the same time the candle itself remains dry, then most often this indicates that gasoline is not downloaded. There may be several reasons in this situation. This, in particular, is about the state of the fuel filter and carburetor.
• ICE of braids for grass is not started or immediately after launch stops working, which can be due to clogging of an air filter that prevents the normal supply of air necessary to enrich the mixture.

In addition to all of the above, owners of trimmers have to deal with more serious troubles. One of these is the wear of the piston group. In such cases, to entrust professionals, which will significantly reduce expenses and extend the life of the tool.

Tips

It is necessary to regularly check for pollution and change the fuel filter in the fuel tank of a trimmer for grass (lawn mower) in time. The fuel filter for its replacement can be easily removed from the tank using a wire hook. The fuel filter is easily clogged with bottom precipitation in the fuel tank, which leads to a deterioration or stopping the fuel supply from the tank to the carburetor of a gasoline trimmer for grass.

For refueling a trimmer for grass, it is not necessary to use ethanol gasoline, since in small two- and four-stroke engines that are not used every day or at least every other day, this is a big problem. Ethanol from gasoline precipitates and turns into resin or varnish, clogging microscopic jacks and carburetor channels.

To maintain a carburetor in purity and good technical condition, you can buy a special additive for fuel for two.stroke engines, which cleanses the carburetor of tarry deposits. The additive price is relatively small and it (additive) is not dangerous.

Also, you should abandon all old metal cans, which over time rust inside. Parts of this rust will cause clogged filters, jackets and channels in the carburetor and, as a result, the inoperability of a gasoline trimmer for grass (or lawn mowers). over, immediately, as a rule, the owner of a trimmer for grass cannot determine where this clogs are taken from.

In no case should you store gasoline in plastic containers from under water. When mixing the fuel mixture, a static charge accumulates, you can “catch” the spark.

Therefore, at gas stations it is not allowed to refuel gasoline into plastic canists, only in metal. Before pouring gasoline in a metal canister, it is better to put it on the ground, so statics are removed from the case.

But there are situations when simple manipulations with a motorcycle do not help. The engine still does not start. In this case, we are in progress, we check the power and ignition system, guided by the rule “the motor does not work if there is nothing to burn or set it on fire”.

In this case, the remains of plastic plastic dissolved in the brutal environment are created in the combustion chamber so terrible things that you will definitely not be able. But you certainly remember how to correctly store fuel.

What to do when the fuel was definitely ordinary, there is a spark, but a trimmer for grass does not start a gasoline? Maybe you just flooded the candle with gasoline. In this case, it needs to be unscrewed, wiped with an unspoken rag and dry. By the way, it will be completely useful to check the spin for performance itself.

What to do when the fuel was definitely ordinary, there is a spark, but a trimmer for grass does not start a gasoline? It is possible that you just flooded the candle with gasoline. In this case, it must be turned out, wiped with a clean rag and dry. In general, when a trimmer for the grass began to act up and stall why a trimmer does not start for grass. By the way, it will be completely useful to check the candle for performance itself.

There is no need to save here. You must understand that the cost of repairing the cylinder-piston group can be 2/3 of the cost of the tool itself. Perhaps a significant argument to buy an additive to the fuel of a well.known brand, for example, Husqvarna, Oregon or Champion, and 92nd gasoline at gas stations with a good reputation.

Proportions must be followed by those indicated in the instructions for the operation of the benzo tool.

Make the fuel mixture to develop in 2 weeks. Further domestic gasoline begins to lose its octane properties, a chemical reaction of the interaction of gasoline and oil will go, and you will begin to attend torment with the launch of a chainsaw, motorcycles, benzotrimer. The stagnant mixture is better to utilize, and it is better not on the beds of an envious neighbor. The mixture should be fresh. Last year’s gas should not be!

Suppose you don’t start a trimmer for grass. In this case, the first thing is to check whether the fuel is enough in the tank, as well as evaluate the quality of the fuel mixture. To refuel a motorized unit, it is necessary exclusively high.quality gasoline. It is recommended to use fuel, the brand of which is not lower than AI-95.

Why is a trimmer not starting for grass gasoline? Incorrect preparation of the fuel mixture may also lead to this, which consists of oil and gasoline. The proportions in which the specified components are connected are indicated by manufacturers in the guide for the operation of a trimmer for grass. Preparing the fuel mixture is extremely not recommended in large volumes, that is, for the future.

Another common cause, due to which a trimmer for grass does not start, is the presence of a blockage in the filter area. To confirm the conjecture, just dismantle the indicated block and try to start the unit without it. If the engine of the trimmer for the grass has launched, most likely you will have to replace the air filter or at least perform a thorough purge of the old.

In the presence of abundant contaminants on the surface of the filter element, it is necessary to use a new grid. Relying to such actions, you should not leave a suction pipe at all without a filter. After all, rush in this case can lead to the need to repair the entire piston group of the unit engine.

• several screwdrivers (slotted and cross.shaped);
• set of wrenches;
• car compressor (there is a driver in the trunk of a self.respecting);
• container (you can PET bottle);
• Pure rags.

Search for faults is carried out on the principle: from simple to complex. The reasons why the supply of gasoline to the carburetor is violated:

• Remember when the fuel filter changed the last time. Perhaps he is simply clogged with mud;
• Water fell into the gas pipeline, and an ice cork was formed (relevant for minus temperature, “treated” with a mug of hot water);
• Lack of pressure in the fuel line. banal leaks in the joints. Pay attention to if there is a smell of gas around the car after trying to start;
• There is an obstacle in the hose from the gas tank. a piece of rust, a cork from dirt;
• A breakdown of a gasoline pump;
• Clogging of a cell filter near the fitting in a carburetor.

To determine the location of the malfunction, there are two primitive, but effective methods of verification:

• Remove the rod of fuel supply, and press the lever of manual swing several times. If the fuel comes, then the pump is working, we continue to search for the cause in the carburetor. The fuelboard from the tank to the pump is also working;
• We collect a little gasoline into the container, connect to the fuel supply hose, and place the bottle as high as possible. Try to start the engine. If the motor has started. the reason is in the chain: gas tank, fuel, filter, pump.

Next, we are looking for a reason in localized nodes.

On the test machine, the engine air filter is located right on the carburetor. Therefore, for access it must be disassembled.

• Remove the filter lid using the key. We take out the filter element (at the same time check its cleanliness) and turn the casing bolts to the carburetor. Remove the case;
• We look inside the carburetor. Depending on the engine temperature, the throttle can be open or closed. In the second case, open it with your hand. Then we click on the drive of the throttle mechanism, and check whether a stream of gasoline from the pump appeared;
• After making sure that there is gasoline in the carburetor, we get in the car, click on the gas, and try to start the motor. If it does not start, we look further;
• Remove the top cover of the carburetor so that the fuel level in the carburetor chamber becomes visible. The cover is attached to 5 screws. You should also disconnect the bracket of the gas cable, and turn off the idle valve;
• Having freed the float chamber, we evaluate the level of gasoline. With normal operation of the fuel supply system, the level should be lower than the walls by 23 mm. You can evaluate the level with the tail of the caliper, having previously exposed it to a depth of 22-23 mm;
• We put on the lid back, fix it with a pair of screws, and again we start the motor, having previously drowned the gas pedal before the stop;
• If the camera is empty, the test algorithm is slightly different. We put on the lid, leaving a small gap between the upper edge of the float chamber and the plane of the cover. We fix the gap with a flat steel ruler or a small screwdriver;
• Fill the camera with manual swing or checking the crankshaft for several revolutions by the starter. After filling out the camera, we try to start again, having previously fixed the lid;
• The motor earned. this is a sign of a needle valve malfunction. It should be replaced, since it is almost impossible to restore it.

Even if in this case the trimmer for the grass does not start, the quality of the contact between the high.voltage wire and the light of the ignition should be evaluated. In the absence of a spark (if there is a reliable connection between these elements), the problem will probably be caused by a malfunction of the ignition unit. In this situation, you will need to contact the services of the master who will reinstall the site.

Another common reason why the trimmer for grass does not start is the garbage in the filter area. To confirm the assumption, just disassemble the device and try to start the device without it. If the trimmer engine is launched, you probably need to replace the air filter or, at least, carefully clean the old. If there is strong contamination on the surface of the filter element, you must use a new grid. This should not leave the suction pipe completely without a filter. Indeed, success in this case can lead to the need to repair the entire piston group of the engine.

Cleaning the respirator

Most often, the engine of branded models of trimmers stops due to clogging the respirator. The main task of this component is to align the pressure in the fuel tank. In the case of blocking the block, a vacuum forms here, which significantly complicates the supply of fuel. This problem can be eliminated by cleaning the respirator with an ordinary sewing needle.

The stable work of a trimmer for grass can be disturbed due to accumulation of dirt in the exhaust channel or the formation of a blockage on a muffler. This problem is most often found during the operation of old trimmers models. The problem is solved by dismantling the anti.diplomatic mesh and its cleaning.

Proper care for the chainsaw

There are no unnecessary phrases in the operating instructions, everything that is proposed is aimed at uninterrupted operation of the gasoline pump. Cleaning all parts after each cycle of work facilitates the removal of unexplored residues and dirt. Clean only chilled nodes. This method contributes to the quality of the air cooling of the engine and the gearbox.

For refueling, you must use fuel with recommended oil in the instructions. If the fuel mixture remains in the fuel tank, the oil will swim and, when starting, land on the damper, worsening its adjustment. The mixture may besiege and clog fuel in the carburetor.

When saving the equipment for the winter, inspect, lubricate the gearbox and the piston system, wrap the entire saw in a lubricated rag and store it in a dry place.

This is impossible, dangerous for the instrument and health of the mower, use a metal cable instead of fishing line. It cuts more efficiently, but the load on the gear and the engine increases. A worn piece of wire flies at the speed of a bullet during disconnection. Effective mowing can lead to the rapid wear of the piston group of the engine. For greater efficiency of the mowing, it is proposed to use the profile of the “Asterisk” line.

While leaving the personal plot, sometimes people have to face the fact that their lawn mower is not started. There are several reasons for the refusal of this tool.

The lawn mower will not start. the reasons

Incorrect storage, a long break in extreme, untimely maintenance and other factors lead to the fact that the lawn mower may stop starting.

Diagnostics of the reasons should be started with checking the main nodes. fuel tank, candles and candle canal, air and fuel filters, saopan, graduation channel. Most often, problems are associated with one of these nodes, and their thorough inspection will help to decide why the lawn mower will not start.

If you use low-quality fuel (below AI-92), this can lead to a breakdown of the cylinder-piston system, the repair of which will result in about a third of the cost

In addition, it is important to observe the correct ratio of gasoline and oil specified in the operating guide to your specific model

The operation of the engine can also prevent fuel filter pollution. If this problem is detected, you need to replace the filter. Air filter also does not hurt to check also. When contaminating it, it is necessary to dismantle it, rinse in water with detergents, dry, grease in oil and put in place. Spark plugs that do not show signs of life must be replaced with new.

Sometimes the lawn mower starts up normally, but then stalls. This is mainly due to incorrect tuning the carburetor or its reservation. Determine that the reason is precisely in this, you can by vibration that are noticeable during operation. You need to configure the fuel supply adjustment, following the instrumentation instructions.

The lawn mower is poorly started on hot

When the lawn mower worked properly, and after a short break does not want to start again, you need to press the gas trigger and sharply pull the starter cord several times in a row, until the engine starts and only then release the gas trigger.

The lawn mower is not started on a cold

At the factory, cold motorcycles are pressed for gas, on the contrary, is not recommended. It is necessary to tilt the lawn mower so that the air filter is at the top and click on the leak button 5-6 times, then install the function of switching the functions to the Start position and pull over the cord several times before the engine factory. After a few seconds of operation, braids for the grass, the start system can be turned off.

What to do if the lawn mower does not start ? In this article we will consider the main reasons for this breakdown.

Most often, the lawn mower refuses to start because the fuel fills the candle. This can happen due to the fact that worn nozzles serve too much fuel in the combustion chamber, and its excess flies a candle, which is why it cannot generate a spark. If the candle is always wet, then this may indicate the wear of the gaskets, which is why the flowing oil prevents the formation of a spark. If the candle is dry, and the lawn mower still does not start, then, first you should replace the candle itself.

Another common reason-a 4-step lawn mower refuses to start “on hot”. Here you can recommend a simple test: by clicking on the trigger, twitch the launch cord several times. If after that the engine has not started, then your tool needs a more detailed diagnosis with subsequent specialized repair.

When it is necessary to adjust

Carburetor adjustment is necessary in the following cases:

• The new engine was running out (4-5 liters of fuel mixture were used);
• The composition of the fuel has changed (brand of oil and gasoline);
• The weather changed (it became hot, cold);
• Air vacuum has changed (concerns mountainous areas);
• after long.term storage;
• the load on the engine has increased (after changing the tool and t.D.);
• Due to the vibration, the adjustment screws spontaneously unscrewed;
• Fuel consumption has increased, the carburetor shimmers the fuel;
• Flapse quickly appears on the electrodes of the candle (while the fuel mixture is prepared correctly);
• The motor starts and immediately stalls or is poorly gaining momentum;
• Gasoline does not enter the cylinder;
• A large amount of exhaust gases.

How to avoid most problems?

The work of this seasonal equipment is very affected by its proper storage. over, this applies not only to a long “rest” in the winter, but also of short intervals of inaction. To protect yourself and the technique from problems, you need to adhere to a few simple recommendations.

• Before sending on a well.deserved rest, a tank trimmer for grass is freed from fuel remnants. To remove the entire mixture, the lawn mower is launched and allowed to work until the engine is stalled.
• The first operation after “winter hibernation”. pouring a small amount of oil into the candle hole. Before that, the piston is moved to the extreme position. Such a lubricant will facilitate the launch and prevent premature wear of the details.

Before starting working with a motorcycle, they must check the candle and all the main equipment components.

Reasons why the trimmer for grass does not start is quite a lot. But most of them can be detected and fixed independently. The main thing is the correct diagnosis, attentiveness and sequence of actions. And about how you can cope with problems, the master from the next will tell in detail

The main thing. Fuel mixture!

In this case, the remains of plastic plastic dissolved in the brutal environment are created in the combustion chamber so terrible things that you will definitely not be able. But you certainly remember how to correctly store fuel.

What to do when the fuel was definitely ordinary, there is a spark, but a trimmer for grass does not start a gasoline? Maybe you just flooded the candle with gasoline. In this case, it needs to be unscrewed, wiped with an unspoken rag and dry. By the way, it will be completely useful to check the spin for performance itself.

Correct starting correctly!

Often, trimmers for grass do not start after they try to “put them into operation” after a long storage. Troubles with starting in this case are often justified by the incorrect actions of the user.

If you are faced specifically with this phenomenon, then when you cool, you need to close the damper, then pump up a small amount of fuel consistency in the carburetor. Then stretch the starting hand to the sensation of resistance, after which, with sharp and energetic movements, start a trimmer for the grass.

Do.it.yourself 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 enriching 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.

The alternate execution of these actions will correctly configure the fuel node of the trimmer for the grass, without the risk of exceeding the permissible load on its main working mechanisms.

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).

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.
