Question: How To Adjust The Carburetor On A Poulan Pro Chainsaw?

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 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.

If your chainsaw only runs with the choke on, it is likely an issue with your carburetor. If the carburetor is plugged, the engine will be starved of fuel and will not run. However, if the engine is plugged, the choke will pull more fuel through the carburetor’s idle circuit and allow it to run.

The screw on top — marked “T” — is for adjusting the fuel mixture while the engine is idling.
