Trouble starting your chainsaw? It's time to face the fix. Whether you are a legendary lumberjack or a weekend woodworker, eReplacementParts.com provides the parts, procedures and facts you need to fearlessly fix what fails you.
The choke knob attaches to the choke plate lever on the carburetor. When the choke knob is pulled out, the choke plate (on the front of the carburetor throat) is rotated to the choked position. The choke draws additional fuel into the carburetor during a cold start.
After years of use, the arm that connects the knob to the choke lever may become fatigued and break off. The knob might get broken accidentally by dropping the saw, kicking the choke knob (often during starting), or if something falls on the saw.
This article provides step-by-step instructions for removing and installing the choke knob on a Poulan chainsaw.
