If at low revs the saw engine runs smoothly, and when they increase, it stalls, then the problem is connected with the muffler. This indicates a defective spark arrestor. Most likely, he was clogged with combustion waste. To perform cleaning, the silencer is first removed and disassembled. Further, the user painstakingly removes the resulting deposits with a detergent.
After this fact, experts advise to dry the part with a hairdryer. At the end of all manipulations, the muffler is installed in its original place.

An irreplaceable thing for a summer residence. I use for construction, logging and cultivation of trees. The saw is light, reliable, works equally well in winter and summer. I like build quality, ergonomics and reliability. There are no problems with maintenance. The parts are inexpensive.
A chainsaw is an extremely useful tool for gardeners, summer residents, owners of country houses or their own bathhouses. And we do not take into account professional use in forestry, carpentry or in construction.
Saw Husqvarna 137
This saw has gained popularity due to the optimal balance of its characteristics and high quality. This saw can be called ideal for domestic use:
- It is quite light, only 4.6 kg in an unfilled condition;
- It has a good power of 1.6 kW, which allows you to solve a variety of problems;
- Equipped with vibration damping systems and chain brake, which increase the convenience and safety of work.
Husqvarna 137 is a versatile household saw. Thanks to the thoughtful design and high build quality, the saw will last you a long time, even with intensive work.
However, like any mechanism, Husqvarna 137 may begin to “act up.” Consider the main malfunctions characteristic of this saw model:
Since the malfunctions of this system are the most common, the spark plug should first be inspected. If it is completely dry, then it must be installed in place, and look for the cause of the breakdown in another place.
If there are traces of fuel on the candle, then the malfunction is really somewhere nearby.
Wipe off the spark plug, turn off the fuel supply and turn on the starter. This will get rid of excess fuel in the combustion chamber. After that, install the spark plug in place, check the carburetor adjustment in accordance with the instructions, and carry out the start strictly following it.
Another problem is the presence of soot on the candle. Besides the fact that it needs to be cleaned, you also need to reconsider your approach to the oil used. Sludge appears due to poor quality oil, which not only complicates the operation of the ignition system, but also contributes to the root wear of other parts of the saw.
If cleaning the plug and purging the combustion chamber does not help, check the gap between the electrodes and the plug. You can correct it using a new gasket.
In cases where the spark is completely absent even when replacing the spark plug, it is advisable to contact a specialized workshop, since the problem can be caused by a malfunction of the high-voltage cable.
Fuel supply system.
First, check the carburetor adjustment.
If fuel still does not flow into the cylinder, remove the fuel hose and check the fuel supply. A weak jet indicates a problem in the fuel filter. It must be washed in water, dried and put back.
Similarly, check the air filter. Inadequate airflow into the carburetor can cause the engine to stall.
After flushing the filters, inspect the system for foreign particles that may interfere with the flow of fuel.
If all else fails, the cause of the malfunction may be in the carburetor itself, and this is already a complex device, and it’s better to turn to professionals.
When the saw dies with increasing speed, it is advisable to check the muffler. A spark arrestor is placed there, which is often clogged with various combustion products. To eliminate the malfunction, the muffler should be well cleaned.
The remaining breakdowns of the chainsaw, as a rule, are more serious and require qualified repair.
