How to Adjust the Carburetor on a Poulan Pole Saw

To adjust the carburetor on a Poulan pole saw, you have to turn a screw to increase or decrease the saw’s idle speed. By increasing or decreasing the idle speed, you can better control the saw’s acceleration and deceleration, increasing overall performance. As the saw ages, and the mixture of gas to air becomes unbalanced, you will need to adjust the carburetor to rebalance the gas-to-air ratio in the carburetor.

  Fill the Poulan pole saw with fresh gas. Start the saw in an area where the chain can’t hit anything while you are adjusting the carburetor. Let the engine idle for several minutes to warm up.

  Locate the idle speed screw on the carburetor, on the back end of the saw. Turn the screw clockwise until the engine speeds up and the chain starts moving.

  Turn the screw counterclockwise until the engine slows down and the chain stops moving. Turn the idle screw to the maximum rpm before the chain begins to spin.
