Petrol trimmer echo will not start

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. Repair or replacement of the piston group will cost you too much (sometimes up to 70% of the cost of a new tool). Prepare the oil-fuel mixture strictly according to the instructions. Calculate its amount based on real needs. Excess gasoline left over after work loses its quality over time.

Wet spark plug on the gas trimmer. Flooded engine

Surely many who use small motorized equipment know what a “flooded” spark plug on an engine is and what unpleasant situations arise because of this. Very often, using newly acquired equipment, many do not check the condition of the spark plug electrodes after updating the fuel and lubricants, and remember this only when the first malfunctions appear.

Troubleshooting strategy

Where to start troubleshooting if the trimmer won’t start? In situations where the tool stalls immediately after starting, it is worth inspecting the following units of the unit:

  • fuel tank;
  • spark plug;
  • fuel and air filter;
  • outlet channel;
  • breather.

It is the breakdown of the above locations that most often leads to the fact that the trimmer does not start well. Let’s see how to eliminate such troubles.

Breather cleaning

Often, the engine of branded trim models stalls as a result of a clogged breather. The main task of the specified component is to equalize the pressure in the fuel tank. The reasons why the gasoline does not start and you never know what other reasons may be. In case of contamination of the unit, a vacuum is formed here, which significantly complicates the supply of fuel. The problem can be eliminated by cleaning the breather with a regular sewing needle.

Checking the fuel mixture

Let’s say your trimmer won’t start. In this case, the first step is to check if there is enough fuel in the tank, and also to assess the quality of the fuel mixture. Petrol trimmer won’t start? Causes and the gasoline trimmer is not the spark plug. Why won’t the petrol trimmer start? The reasons why the petrol trimmer stopped starting may be different, so a step-by-step diagnosis of the device is required. It is necessary to refuel the motorized unit with exclusively high-quality gasoline. It is recommended to use fuel, the grade of which is not lower than AI-95. Filling the trimmer with fuel of unknown origin not purchased from a gas station can cause frequent tool malfunctions. This can cause damage to the piston-cylinder system. In this case, repairs often exceed the cost of the device itself.

Some tricks for working with the petrol trimmer.

How to prevent sudden breakage during trimmer operation?

In order for the unit to always be in a functional state, it is worth following a few simple rules:

  • Conduct a timely, regular technical inspection of the main mechanical components of the device.
  • Fill the trimmer with only fresh fuel, the quality and origin of which is beyond doubt.
  • After each use of the tool, check whether oxides and carbon deposits have formed on the surface of the ignition system components.
  • Avoid heavy load on the trimmer during work.

In order for the unit to remain in working order, it is necessary to properly prepare it for storage in the winter. First of all, you should completely disassemble the instrument, and then flush and clean the constituent elements. It is also important to inspect the functional blocks for damage, if necessary, eliminating the deformation of parts, all kinds of distortions, gusts of materials.

Trimmer won’t start after winter

How to be in such a situation? Don’t worry and panic. This is a very common problem that can be solved in just 3-4 minutes. Firstly, if last year’s fuel remains in the gas tank, then it must be drained. Gasoline loses its octave properties after 2 weeks of inactivity. Secondly, you need to start a lawn mower after a long stagnation in a slightly different way. First you need to open the throttle and pump a little fuel mixture into the carburetor, then pull the handle until you feel a little resistance. After that, you can start the trimmer.

Trimmer won’t start. Why?

A petrol trimmer is a surprisingly useful thing that can be used to clean up not only a miniature lawn in the backyard of the house, but also mow a lawn of considerable size without any extra hassle. But, like all things in this world, it tends to break. In this article we will try to figure out what to do in cases where the trimmer refuses to work.

Petrol trimmer does not start well

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. Remember that, for example, trimmers of the brands “Stihl” and “Husqvarna” are unlikely to start on fuel quality lower than AI-92. You should not save on fuel, because repair of parts of the cylinder-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.

Trimmer starts and stalls

If, when you try to start the trimmer, it starts, but immediately stalls, then the air filter may again be the reason for this. It is necessary to remove it and check if it is clogged with dust. If this is true, then you need to thoroughly clean it or purchase a new one. Also, the problem may lie in the malfunction of the ignition coil. In this case, it is better to take the mower to a service center.

Why the petrol trimmer won’t start?

The owner of a summer cottage cannot do without a lawn mower or trimmer. But during 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.

Why the trimmer won’t start. reasons

To determine why the gasoline trimmer does not start well or constantly stalls, it is necessary to consistently check the operation of all the main components of the unit. This is especially important after long-term storage of the lawn mower. So, the main reasons for this behavior of the trimmer are as follows:

  • The culprit that the lawn mower will not start may be a poor-quality oil-gasoline fuel mixture. It must be cooked strictly according to the instructions. Saving is not at all appropriate here, since it can lead to the failure of the entire piston group of the trimmer. Do not prepare too much fuel mixture, as excess gasoline will lose its quality over time.
  • Be aware that petrol trimmers of brands such as Stihl, Husgvarna and some others will not start if they are filled with cheap petrol with a low octane number. Therefore, for such units it is necessary to use only high-quality high-octane fuel.
  • If the trimmer stalls immediately upon start-up, then it may have a flooded candle. In this case, you need to unscrew it and dry it thoroughly for half an hour. Then drain the excess fuel that is in the chamber, clean the candle from carbon deposits, put it back and try to start the lawn mower.
  • If your new gasoline trimmer won’t start, there may be a lack of spark. And this happens because the socket where the candle is located is dry and the fuel does not ignite. Lightly moisten the thread of the spark plug with a few drops of gasoline.
  • The gasoline trimmer may stall due to clogged air or fuel filters. It is best to replace such elements with new ones.
  • The exhaust port and breather can also become clogged. Having cleaned these trimmer elements, it will be possible to start the unit without any problems.
  • Another reason why the petrol trimmer won’t start, even when there is a spark, may be a clogged carburetor. To clean the channels and nozzles, it is necessary to blow them with compressed air using a compressor. Can be used to clean the carburetor and special rinse.
  • If the carburetor gaskets are worn out, they must be replaced. And if the tightness of this device is broken, you will have to identify the faulty carburetor part and replace it.
  • The trimmer may not start due to wear on the piston group. However, it is better to change such parts of lawn mowers in a service center.

Filter check

Another common reason the trimmer won’t start is if there is a blockage in the filter area. To confirm the guess, it is enough to dismantle the indicated block and try to start the unit without it. If the trimmer engine starts, most likely you will have to replace the air filter or at least thoroughly purge the old one. If there is abundant dirt on the surface of the filter element, a new mesh must be used. When resorting to such actions, do not leave the suction pipe completely without a filter. After all, haste in this case can lead to the need to repair the entire piston group of the engine unit.

Diagnostics of the candle channel

What to do if the used fuel mixture is in good order, but the petrol trimmer still won’t start? The reasons for the failure of the mechanism may lie in the excessive moistening of the candle channel. To diagnose and fix the problem, you must do the following:

  • Unscrew the candle. Wipe it thoroughly and then dry it.
  • Drain excess fuel in the chamber through the appropriate plug hole.
  • Clean old spark plug if there is carbon deposits on its surface. To cope with the task will allow the use of a regular ladies’ nail file or a file.
  • When installing the element in place, set a gap of 1 mm. To check the parameter, it is enough to place any coin in the gap.
  • Assemble the functional block back.
  • Try to start the trimmer.

It is recommended to dry the candle channel for at least half an hour. However, in no case should you resort to calcining its elements. After all, heating the spark plug can lead to its final damage. What to do if the function block was serviced in accordance with the above recommendations, but the trimmer does not start, there is still a spark? In this case, it is worth treating the threaded connection with gasoline. The latter does not need to be abundantly impregnated with fuel. It should only be slightly damp. Such actions should be taken to ensure ignition. After all, no matter how strong a spark the candle gives, there will simply be nothing to ignite in an absolutely dry chamber.

If, even in this case, the trimmer does not start, it is worth assessing the quality of the contact between the high-voltage wire and the candle. In the absence of a spark (if there is a reliable connection between these elements), most likely, the problem is caused by a breakdown of the ignition unit. In this situation, you will have to turn to the services of wizards who will reinstall the node.

Off-season petrol trimmer storage tips

When storing the trimmer, it is worth filling the gearbox with enough oil. Then you need to clean the air filter, partially disassemble, blow out and rinse the engine of the unit. After drying all mechanisms, the moving elements should be lubricated. To process the piston system with oils, you must first remove the spark plug. Then you need to move the piston to the extreme position, then pour a small amount of oil into the spark plug hole and rotate the crankshaft. If you do not plan to store the petrol trimmer in the off-season in the house, it is recommended to tightly wrap the engine of the unit with an oiled rag. This will avoid the development of corrosion on the surface of important parts of the mechanism.

Why won’t the petrol trimmer start? Improper preparation of the fuel mixture, which consists of oil and gasoline, can also lead to this. The proportions in which these components are connected are indicated by the manufacturers in the trimmer instruction manual. It is highly discouraged to prepare a fuel mixture in large volumes, that is, for the future. Indeed, with long-term savings, there is a loss of the defining properties of the substance. Therefore, if the trimmer does not start, it is worth draining the old fuel and using a freshly prepared fuel mixture.
