Poulan Starter Pulley. It is important to know that the starter pulleys for your Poulan Chainsaw are not the same as idlers. The difference is that an idler rotates freely around bearings at its center, while a pulley has a notch (or some other device) to fix it to a shaft as it rotates.

A Poulan chain saw carburetor has a single feature to adjust with a tool to increase or decrease the idle speed. The carburetor is set correctly at the factory, but adjustments can be necessary if the engine runs poorly, dies or runs at a high speed. Engines that run at too high of a speed can be destroyed or run inefficiently. Engines that run at a slower speed than normal will stall and quit, then need restarting often.
Carburetor Function

A Poulan chain saw carburetor operates in the same manner as a carburetor on an automobile or other small engines. The adjustments to it either make the fuel mixture richer, by adding more fuel and oil to the air mixture, or leaner, by reducing the fuel and oil mix ratio to air.
Idle Speed Problems
Adjustments need to be made to a carburetor when it dies after starting, is hard to start or dies under a load. In these cases, the fuel and oil ratio to air needs to be enriched. If the chain saw sounds as if it is running too rich, it will rev at high speeds and make a high-pitched sound. In this case, the mixture should be leaner to prevent engine damage.
Safety First
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.
High and Low Speed Adjustments

To adjust the carburetor idle speed, locate the idle speed screw labeled with a 'T' just above the primer bulb. Start the chain saw as you normally do and let it idle, making sure the chain does not touch anything. Insert a small flat-head screwdriver into the idle speed screw and turn it clockwise to increase the engine speed if it idles too slowly. As soon as the chain starts to move, turn the screw counterclockwise until the engine idles without dying and the chain stops moving for the correct idle speed.
