How To Adjust Carburetor On Poulan 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.

How do you adjust a high and low carburetor?
