When adjusting the carburetor, you need to place your Poulan chain saw on a flat level surface with the chain overhanging the surface, or move all items so it will not come into contact with anything. The chain is moving during the adjustment process, so you should wear personal protective gear including safety glasses, a long-sleeve shirt, long pants, closed-toe shoes and leather gloves.
In the same way as a carburetor on an automobile or other small engines works, a Poulan chain saw carburetor works in the same way. Before you can adjust the carburetor on your Poulan chainsaw, make sure it’s on a flat, level surface with the chain hanging over the edge, or clear the area of anything that might get in the way of the chain. If the engine is idling too slowly, insert a tiny flat-head screwdriver into the idling speed screw and crank it clockwise to boost the engine speed if necessary.

What is the T screw on a Poulan chainsaw?
The screw on top — marked “T” — is for adjusting the fuel mixture while the engine is idling. Of the two underneath it, the one on the left is for adjusting the mixture when the engine is running a low speed, and the one on the right is for making the same adjustment when the engine is running at high speed.
Why won’t my Poulan chainsaw keep running?
Over time, the spark arrestor can become clogged with soot. If the spark arrestor is clogged, the chainsaw may run stall or run rough. To unclog the spark arrestor, remove it and clean it with a wire brush. You can also replace the spark arrestor.
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.
Why is my Poulan chainsaw bogging down?
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 only run on choke?
When your chainsaw only runs if the choke is on the problem, in most cases, is a result of fuel supply problems or a faulty carburetor. To fix the problem you should check and clean the fuel system and carburator.
How do I adjust the idle speed?
Turn the idle screw, now exposed from the protective rubber coating, in order to adjust the idle. Loosen the screw in a counter-clockwise fashion to increase idle speed or tighten it in a clockwise manner in order to decrease the idle speed.
