If the Husqvarna 142 starts up and immediately stalls, the main reason for this lies in the wear of the rings, which leads to loss of compression. If the engine starts and stalls during cold start, then you should check the muffler, as well as the contact between the high-voltage wire and the spark plugs.

To fix the malfunction, you will need to disassemble the saw, and inspect the piston rings. If necessary, they must be replaced. It will not be superfluous to clean the cylinder walls of the remaining fuel.

If the rings are working, then you need to inspect the contact between the spark plugs and the chainsaw wire. You also need to clean remove the muffler and inspect its walls. As a result of prolonged use of the tool, a thick layer of soot accumulates on the walls of the muffler. In this case, it will be necessary to purge the element with compressed air from the cylinder.

After performing all of the above procedures, you need to assemble the tool, and start it. Before using the saw, it needs to be given a few minutes to warm up the engine. Then you can continue to use the tool in normal mode.
