Checking the fuel mixture

Before starting the engine of the gasoline streamer, check the presence and quality of the fuel mixture. Do not save, do not be greedy and “do not be clever” in this matter.

But here we must also not forget about the Chinese marriage. They even balance the shafts on the knee, install the cheapest bearings, and stamp carburetors with clogged channels.

So what if the petrol trimmer won’t start well or won’t start at all? The most common reason for such a breakdown is poor quality fuel.

The piston group can be one third of the total cost of the scythe, and sometimes even half. Also, when preparing the fuel mixture, it is necessary to correctly observe the proportions of fuel and oil, which are always indicated in the instructions for the trimmer.

What to do if high-quality fuel is poured into the gas tank, there is a spark, but the tool still refuses to start? It is necessary to check the condition of the candle. It is located in the center of the mower body. It must be carefully unscrewed and make sure there is no plaque on it. If there is, then carefully clean the candle from carbon deposits and dry it.

If the lawn mower does not start even after the methods suggested above, then you need to try to remove the air filter and start the device without it. If the trimmer still does not work, thoroughly dust the old filter or buy a new one.

It also happens that the mower works for a maximum of 5 minutes, and then stalls and does not start until it cools down. In this case, try opening the filler cap of the gasoline filler cap. a suction sound should appear. Then screw the cap back on. If you do this manipulation while the trimmer has just started to stall, then the speed will be restored, and you can continue to work. If the mower stalls before opening the lid, then you just need to start it as expected according to the instructions.

First you need to bring the red toggle switch on the trim bar to the “I” position. This means turning on the power. Then you need to switch the fuel supply lever on the carburetor and use the fuel “suction” button (similar to a pipette, located on the carburetor).

Why won’t the trimmer start (petrol)?

Because he worked his way. Why, there can be any number of answers to this question. Bad fuel is far from an argument. Maybe a person doesn’t know how to use it, and that’s why it’s wrong.

There is also such. hand hooks.

There may be several reasons why the petrol trimmer won’t start.

If the trimmer does not start or immediately stalls after starting, then the problem may be in the fuel tank (namely, as fuel), in the spark plug and sluice duct, in the air or fuel filter, in the breather or in the exhaust duct.

1). It is imperative that before starting the trimmer, you need to check the availability, and most importantly, the quality of the fuel mixture.

2). The trimmer may not start or stall when the spark plug is flooded. It will need to be unscrewed and wiped.

You need to dry the candle channel for at least 3040 minutes. Otherwise, a new candle may also fill up.

3). If the trimmer starts without an air filter, then it is better to replace the old filter with a new one.

4). Trimmer may not start if fuel filter is dirty.

  • The fuel mixture does not flow into the carburetor. Pump her up a little.
  • The ignition coil is out of order.
  • The muffler is clogged. It is necessary to free it from carbon deposits. To do this, carefully disassemble and clean (you can burn on a gas burner).

Usually, our trimmer would not start after winter, and we used to take the trimmer to the workshop almost every spring, where it was repaired to us. But, once, a knowledgeable person advised us in. First, never leave gasoline in the trimmer for the winter, because old gasoline can be the reason that the trimmer does not start, and he also said that it is necessary for the trimmer factory to pump the carburetor with a fuel mixture. After we began to follow these rules, our problems with the trimmer disappeared.

First of all, you can see the candle. If necessary, replace it, making sure that the plug is not broken and gives a normal spark. The next problem will be lurking in the fuel system. As mentioned above, we check the tightness, then we check the fuel filter, change it if necessary. We clean the carburetor, see the effect. It may be necessary to dig into the ignition system, adjust. To check the fuel system, you can pour a few grams directly into the cylinder through the plug screw holes, screw in the plug and try to start. At least the trimmer should make sounds of the engine running for 1-2 seconds and some smoke should fly out of the muffler.

If the trimmer does not start at all or it stalls immediately after starting, then you first need to look for the cause in the main components and assemblies, for this you need to check in the sequence below, so, this is the sequence:

Reasons why the petrol trimmer won’t start

The owner of a summer cottage cannot do without a lawn mower or trimmer. But in the process of its operation, situations may arise when this unit for some reason stops starting. And there can be many reasons for this. Let’s find out why the petrol trimmer won’t start.


There are not only situations when petrol trimmers do not start, but there are cases when, after starting, they work for a couple of seconds and immediately stall. Inspect the spark plug again: if it is “thrown”, and this situation repeats even after wiping and drying it, go to the “revision” of the air filter.

Perform cold starts correctly!

Often gasoline trimmers do not start after trying to “put them into operation” after long-term storage. But since this has happened the gasoline trimmer will not start the spark plug trimmer. Failure to launch in this case is often caused by incorrect user actions.

If you are faced with exactly this phenomenon, then during a cold start you need to close the damper, and then pump a small amount of the fuel mixture into the carburetor. Then pull the starter handle until you feel resistance, then start the trimmer with sharp and energetic movements.

Adjustment and tuning of the carburetor

The maximum and minimum engine speed, smooth idle speed are regulated by the carburetor. The stable operation of the lawn mower depends on the amount of the supplied combustible mixture and air, their ratio. the lawn mower will not start if the carburetor is not adjusted correctly. The procedure for adjusting the device for supplying fuel at low speed (L), high speed (H) and idle (T) is regulated by the screws of the same name:

  • The chainsaw must run for at least 10 minutes, since the adjustment is carried out hot.
  • Screw H is turned smoothly to maximum speed, then turned by ¼, counterclockwise, reducing the speed of rotation of the engine shaft.
  • Idling is adjusted with the screw T, ensuring that the scythe does not rotate.
  • The screw L is adjusted, at first opening the maximum throttle, and then smoothly reducing the speed to stable minimum.

After adjustment, a serviceable carburetor with cleaned filters and a checked ignition must ensure the engine is running. In the event of a carburetor malfunction, after repairing it, you will need to adjust the feed system again before starting the lawn mower.

Rare breakdowns that prevent lawn mowers from working can be:

  • Rewind spring defective;
  • Broken or stuck starter pulley;
  • Defective starter assembly.

The most important malfunction, the elimination of which is associated with replacing the engine, may be the failure of the engine piston group. The cost of repairs will cost about 70% of the cost of the product. Understanding the reasons why the lawnmower won’t start will help:
