FAQ: How To Adjust Poulan Chainsaw Carburetor?

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 chainsaw dies when I give it gas?

Because your chainsaw will idle, but dies when it is revved up to full power, it means that the filter is only partially clogged; it will allow enough fuel to the engine to run on idle, but not enough to sustain full throttle. If the filter becomes clogged, not enough fuel will reach the engine for it to run properly.

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

If your chainsaw is bogging down when you give it throttle, this is often a sign of improper gas-to-oil ratio. If there is too much gasoline in relation to the amount of oil used, this is known as a “rich mixture” and can cause the chainsaw to run poorly.

Why does my Poulan chainsaw keeps stalling?

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.

If your Poulan chain saw won’t start, the first thing to check is the fuel. Then turn the saw on, hold it firmly and pull the start rope in short, brisk pulls until it starts.

Why does my chainsaw idle fast?

The most probable – and easiest to fix – cause of chain rotation while the chainsaw engine idles is a poorly adjusted idle setting on the carburetor. The result is that too much fuel is delivered to the combustion chamber when the throttle is released, and the engine doesn’t really slow.
