The gas mower stalls

When purchasing a lawn mower, you need to be prepared for the fact that, like all other similar tools, it may also develop breakdowns that will require repair.

But you shouldn’t immediately run to the service center and pay a lot of money to the technicians who convince you that there is a serious malfunction in the device.

The gas mower stalls high speed on gas

Perhaps the most common complaint related to gas trimmers is: “The trimmer stalls.”

Naturally, the prerequisite for this may be a fairly severe malfunction. The petrol mower does not develop speed, the reason is back. But in most cases the situation is even simpler than it seems at first glance.

To cope with such a problem, first try to figure out its causes on your own, because once you find out the reason, it’s even easier to deal with the problem, and from time to time it even self-destructs.

In essence, the circumstances are when the lawn mower stalls high speed , there are quite a lot of these circumstances.

Another one is the presence of defects in the power system.

Trimmer doesn't dial rpm, what to do?

Gasoline trimmer (motor mower) carburetor repair does not work develops momentum, power loss

Description.

In this case, the lawn mower will stall idle speed. The petrol mower does not develop speed, the reason | funnydog.tv. Misadjustment or incorrect adjustment of the carburetor can lead to dilemmas with the power system.

Misadjustment can be caused by vibrations that occur during the operation of the lawn mower.

Incorrect adjustment of the lawn mower can be corrected by simply adjusting it in accordance with the requirements indicated in the instruction manual.

In addition, from time to time gasoline trimmers may stall due to the fact that the valve located in the gas tank cap is simply clogged or stuck.

To find out, try using the scythe while loosening the gas cap.

If the device operates properly in this mode, clean the valve.

Moreover, the lawn mower may stall due to the disgusting flow of fuel into the carburetor

Why then does the device start, you ask?

Cause This consists in the fact that at first the fuel gradually flows into the carburetor and there is enough of it to operate at increased power.

But then it runs out and at high speeds the engine begins to stall.

As for the carburetor, the problem here may also lie in the fact that its body is very overtightened.

The reason why the lawn mower stalls is high speed on gas, there may also be an air leak.

We are talking about the likely presence of a place through which air can pass during the heating process of the motor.

Besides everything else, don't forget to check the fuel pickup hose. The trimmer does not develop speed. One of the reasons. The problem may be that it holds poorly or is generally cracked.

These are the main reasons why a lawn mower may stall.

Motokosa is not gaining momentum, the cause of the malfunction and its elimination

Description.

Increased fuel consumption and rapid formation of carbon deposits on the trimmer spark plug when using a properly prepared fuel mixture indicate the need to adjust the carburetor. This describes the setting of trimmers with carburetors that have one screw for adjusting the fuel supply.

Carburetor adjustment

Before adjusting the carburetor, flush air filter. It is recommended to wash it after every 10 hours of operation. After this, you can start making adjustments. The example photo shows the carburetor of the PRORAB-8406 petrol trimmer. The numbers indicate the adjusting screws that we will use.

Carburetor adjustment screws for petrol trimmer PRORAB-8406

Purpose of adjusting screws:

1. Fuel mixture supply adjustment screw.
2. Idle speed adjustment screw.
3. Limit screw maximum speed.

Start the lawn mower and wait until it warms up.

Fuel supply adjustment

Start slowly turning the fuel mixture adjustment screw until the engine starts to stall, or until it stalls if you don’t have time to catch the moment. After this, unscrew the screw a quarter turn if the engine does not stall, or half a turn if it does stall. Start the stalled engine. Check by opening the throttle to see how the engine picks up speed. Continue unscrewing screw No. 1 a quarter turn until the engine, when accelerating, begins to confidently gain increased speed. This will be the most economical moment stable operation engine. For the petrol trimmer PRORAB-8406, the adjusting screws are turned clockwise and unscrewed counterclockwise; for some other brands of gas trimmers it may be the other way around.

Idle speed adjustment

Let's start adjusting low speeds. Screw No. 2 limits the return movement of the lever throttle valve- by screwing it, we increase the idle speed, by unscrewing it, we decrease it. Adjust so that the engine runs confidently at low speeds and even a little faster (for better starting), but so that the reel with fishing line or the knife does not rotate, and there is a sufficient reserve of revolutions before they begin to rotate. If the engine is difficult to start, increase the speed by Idling.

Maximum speed limit

After adjusting the supply of the fuel mixture and low speed, check how the lawnmower engine will operate at maximum speed. If necessary, limit maximum speed to required level using a #3 hollow screw. Loosen the locking nut and screw in the screw to decrease the maximum speed, or turn it out to increase. After adjustment, tighten the nut. Setting the maximum speed is necessary to protect the trimmer motor from overheating and the ability to use the start key lock to reduce fatigue of the right hand.

In the future, it may be necessary to adjust the trimmer carburetor. For example, if the engine starts to rev poorly when running at full load, unscrew screw No. 1 another quarter turn. If starting is difficult, increase the idle speed. The operation of lawn mowers can also be affected by weather, and the quality of the fuel mixture. Vibration can cause the adjusting screws themselves to turn.

The spring may interfere

My first attempt to adjust the carburetor of the lawn mower did not yield anything, since the spring of the fuel mixture adjustment screw was in the way. The factory spring turned out to be too thick when compressed and did not make it possible to reduce the fuel supply to the required level. I had to pick up another spring and continue the adjustment after replacing it.

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

From personal experience

Petrol mower or trimmer

A trimmer is a broader concept than a lawn mower, since it can also be electric. A gasoline trimmer and a gas mower are one and the same.

Some authors claim that a trimmer is a weaker tool, in contrast to a more powerful brush cutter, which can be used for mowing bushes. Personally, I have a tool with maximum power 1.7 kW and, as stated in the instructions, capable of mowing small bushes up to 10 mm thick. The user manual is called “Gasoline trimmer...”.

Fuel mixture proportion

I read somewhere that if the operating manual for the lawn mower and the oil canister indicate different proportions for preparing the fuel mixture, you should use the proportion indicated in the manual.

For a long time I did this - excess oil flowed from the engine onto the gas tank and carbon deposits constantly formed on the spark plug, since the manual indicated the proportion for a run-in engine was 1:25, and on the canister - 1:50. After switching to a ratio of 1:50, the appearance of oil drips stopped. The spark plug continued to burn, but with less intensity (the carburetor was not yet adjusted).

Until now, some users of gas-powered tools determine the proportion of the fuel mixture “by eye.” If the amount of oil is underestimated when preparing the mixture, after some time it may appear extraneous sound immediately after starting the engine, gradually disappearing during warming up, and stopping the engine occurs with with a sharp jerk. Continuing to operate the trimmer in this mode will result in its failure.

Cleaning the spark plug

IN worst times working with a trimmer with an unadjusted carburetor, the engine stopped starting after using each tank of fuel. And only after cleaning the spark plug from carbon deposits could work continue.

Fine sandpaper was used to clean the electrodes, and a thin paper clip with a bent end was used to clean the space between the insulator and the housing. First, the electrodes were wiped from large dirt with a rag, then cleaned with sandpaper. After this, the candle was lowered into diesel fuel and the moistened carbon deposits were scraped off with a paper clip from the surfaces of the insulator, the inside of the body and between them. Next, the candle was dipped into diesel fuel several times, which was then shaken off along with the dirt. Sometimes the paperclip cleaning and rinsing procedure was repeated. After this, the candle was wiped dry and was ready for further use.

Incredibly, one tank of fuel mixture with an unadjusted carburetor can be used up in less than 10 minutes - tested in practice when the trimmer was started and operated at high speeds with maximum fuel supply (the adjusting screw was unscrewed much more than normal).

While caring for their garden plots, summer residents periodically encounter the problem that the lawn mower does not start. There are many reasons for tool failure. To correctly diagnose the problem, the owner of a useful unit at the dacha needs to know the structure and operating principle of its individual parts.

Since a gasoline trimmer is a complex device, you must carefully study the operating instructions before starting work. Very often they simply ignore her, or get to know her superficially. As a result, when the tool stalls or refuses to start, the question arises: “Why won’t the lawn mower start?” A long seasonal break in work, improper storage and untimely maintenance of the trimmer will cause a lot of trouble for the summer resident to eliminate the causes.

Where to start diagnosing a lawn mower

If the lawn mower does not start or stalls immediately after starting, it is necessary to sequentially check all the main components and assemblies. The verification algorithm is as follows:

• Fuel tank (fuel quality);
• Candle and candle channel;
• Air filter;
• Fuel filter;
• Breather;
• Exhaust channel.

These nodes are most often the source of the main problems, which can be eliminated after a thorough inspection.

Checking the fuel mixture

Before starting the gasoline scythe engine, check the availability and quality of the fuel mixture. Don’t save money, don’t be greedy, and don’t be “clever” in this matter. Repair or replacement piston group will cost you too much (sometimes up to 70% of the cost of a new tool). Cook oil- fuel mixture must be done strictly according to the instructions. Calculate its quantity based on real needs. The excess gasoline remaining after work loses its quality over time.

We diagnose the spark plug and spark plug channel

If the quality of the fuel mixture is not in doubt, and the lawn mower stalls when starting, then the cause may be a flooded spark plug. Here for repairs regular one will do spark plug wrench(surely every motorist has one) and a spare spark plug.

• We unscrew the candle and wipe it;
• Dry it thoroughly (do not heat it);
• Excess fuel in the chamber is drained through spark plug hole and dry it;
• We clean the old candle from carbon deposits using a file or a lady’s nail file;
• We set the gap with a distance of 1 mm (you can check it with any coin);
• We return everything to its place and try to start the trimmer.

You need to dry the canal for at least 30–40 minutes. Otherwise, there is a risk of re-filling a new spark plug.

If the spark plug is working, the socket where it is located is completely dry, and the lawn mower does not want to start, lubricate it with gasoline threaded connection. It should be slightly moist. No matter how wonderful a spark a candle produces, there is simply nothing to light up in a dry chamber.

If the trimmer engine still does not start, you should exclude a reason such as lack of spark due to poor contact between the spark plugs and high voltage wire. If the connection is good, but there is still no spark, most likely your ignition unit has failed. Here you won’t be able to do without a specialist, since the part is not repaired, but sold as a single unit.

Diagnostics of lawn mower filters

Another reason why a gas scythe stalls may be the air filter. To eliminate this, try removing the filter and starting the trimmer without it. If it works out, then you will have to change the air filter to a new one, or at least blow out and thoroughly clean the old one.

A gasoline trimmer may not start due to contamination. fuel filter. This is the next stage of our algorithm. Here we check the condition of the filter element and, if necessary, replace it with a new one. When replacing, try not to leave the suction pipe completely without a filter; this is prohibited by any operating instructions. Haste can result in repair of the engine piston group.

Breather and exhaust channel

Often, “delicate” branded models of lawn mowers do not start and stall due to contamination of the breather. The main function of this element is to equalize the pressure in the gas tank. When this unit becomes clogged, a vacuum is created in the tank, preventing the supply of fuel. The problem can be resolved by cleaning the breather. You can use a regular needle for cleaning.

Normal operation of streamers with engines internal combustion may be damaged due to dirt getting into outlet channel or clogging of the muffler mesh. This problem occurs on older generation models. The issue can be resolved by traditional cleaning and removal of the anti-spark mesh.

More complex reasons for lawn mower failure

If step-by-step algorithm troubleshooting has not yielded results, and your scythe still does not start or stalls, it is worth inspecting the carburetor and the engine itself. A clogged carburetor can be one of the reasons for unstable operation of the tool. There are three main problems here:

• Clogged channels or jets. All this is cleaned with special washes or blown with a powerful jet compressed air from the compressor. Do not use needles or wire, as the bores may be damaged;
• Worn carburetor gasket. The solution is to replace the failed gasket;
• Violation of tightness. To check this indicator, you can use a regular household tonometer, replacing the pressure gauge with a suitable one. Keep an eye on the readings: if they do not change, everything is fine, but if the pressure starts to drop, it means that some part of the carburetor is faulty. You'll have to find it and replace it with a new one.

If everything is in order with the carburetor, then the gasoline trimmer may not start due to wear on the piston group. If chips, scratches or burrs are found on the piston or cylinder, they should be replaced. Subject to mandatory verification piston rings. A slight luffing of the piston when the connecting rod swings indicates that it is time to change the rings. This procedure is best left to the service center specialists.

Rules for operating and storing lawn mowers

In order for the lawn mower to start well in the future, you need to provide it with good conditions storage and operation:

• During operation, carefully monitor the cooling system, carefully and promptly clean the channels in the housing, as well as the starter fins;
• if necessary, use solvents, kerosene and other detergents for cleaning;
• Do not clean the tool “hot” - let it cool down;
• strictly follow the operating instructions, otherwise you may overheat the engine;
• if you do not plan to use the lawn mower in the next month, you need to drain the fuel mixture from it, because over time it breaks down into heavy fractions that will definitely clog the carburetor channels;
• After draining the fuel, let the trimmer idle until it stalls, this will help completely remove the remaining working mixture.

Before winter storage do the following steps:

• completely disassemble the braid, rinse and clean all the parts you can;
• inspect the parts for damage, if necessary, eliminate distortions, tears, bends and any other defects;
• fill in sufficient quantity oil into the gearbox and clean the air filter;
• you can partially disassemble the motor, wash, blow and lubricate all moving parts;
• in order to lubricate the piston, you need to unscrew the spark plug, use the starter to raise the piston to the outermost dead center, pour a little oil into the spark plug hole and rotate the crankshaft a couple of times;
• If you store the lawn mower outside the house, wrap the engine with oily rags.

Remember, careful adherence to the rules will allow you to forget that it is difficult to start a lawn mower for several seasons.
