How to Replace the Intake Tube on a Poulan Chainsaw (Model P3314)

Chainsaw need a checkup? 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.

Does your saw run erratically? Does it surge up and down, and sporadically die? If so, it might need a new intake tube. The intake tube mounts between the carburetor and the carb adapter. Its purpose is to provide a flexible pathway for air to move from the carburetor to the adapter.

Because chainsaws tend to vibrate significantly while cutting, most chainsaw carburetors attach to the cylinder using a method that provides some flexibility between the two components. This flexibility helps to dampen vibration in the carburetor, so the fuel can flow more smoothly (and not foam due to agitation).

Cracks are the most common forms of damage to the intake tube. Cracks will allow extra air into the cylinder, which will cause the engine to run lean. Because the extra air entering through these cracks is not regulated, the engine will run erratically, and surge up and down.

This problem must be taken care of immediately, because a lean-running engine will quickly cause serious damage to the cylinder.
