A Poulan carburetor parts diagram is available online at the Sears replacement parts website. The diagrams are displayed on the parts ordering pages found by searching for the Poulan's model number.
The Sears parts site is found at searspartsdirect.com. The user enters the model number of his Poulan and selects the carburetor diagram. While the parts diagrams appear to be older scans of paper diagrams and not of high quality, zooming the image with the magnification tool on the web page provides a clear look at all the parts of the carburetor.
The parts are numbered, and an accompanying key details each part, its number, its substitution part number, price and availability. This information can be used to search the Web for other Poulan diagrams.
