The carburetor might be clogged. A clogged carburetor is often caused by leaving fuel in the chainsaw for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the chainsaw engine to stall.

If the mixture of oil to fuel is too rich, too much oil is in the fuel and it leads to the engine losing power and dying. Open the fuel cap and pour the old fuel out of the tank into a disposable container. Mix new fuel in a gas can with a ratio of 50 to 1.
Why does my chainsaw dies when I let off the gas?
If your chainsaw bogs down after pulling the throttle, the air/fuel delivery system needs to be examined.
