FAQ: How To Adjust A Carburetor On A Poulan Chainsaw?

How do you adjust the idle on a Poulan Pro 42cc chainsaw?

If the engine sputters or stalls quickly, the idle speed is too slow. Turn the T-screw one-quarter turn clockwise and restart the saw. If the saw idles too slowly, adjust the T-screw another quarter-turn clockwise and check it again. Repeat this process until the saw idles without stalling.

Why does my Poulan chainsaw dies when I give it gas?

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

Why does my chainsaw bog down when I give it gas?

How do you adjust a Poulan Pro?
