This genuine OEM sourced replacement part which is specially designed for use with Poulan hedge trimmers. The purpose of this part is to mix the air and the gas before the combustible mixture goes to the engine. If the engine won't start and the tank is full of fresh fuel, or if the engine starts and then quickly dies, the carburetor is likely the problem. Keep in mind this high-quality metal body carburetor is sold individually, please note it includes two durable composite material gaskets that will help ensure an air-tight seal.

Removed the carb. and gas tank. Replaced the fuel filter and tubes. Replaced the carb. using the single new inner gasket. Luckily the outer gasket was in good shape.
After replacing the parts the trimmer runs great.
This trimmer was a donation to a non-profit I work with and it really helps us to control expenses getting quality and fair priced parts for such items.
