3 Reasons to Run Your Chainsaw Carburetor Dry Before Storage

Ethanol in modern gas attracts moisture and leaves a varnish when it sits for months. That varnish plugs the tiny passages in your carburetor, forcing you to rebuild it instead of cutting wood in spring.

Running the carburetor dry clears the fuel bowl and lines of leftover gas. On your last use, disconnect the fuel line or turn off the fuel valve, then let the saw idle until it dies from starvation.

Fuel stabilizer helps, but it is not a substitute for running the carburetor dry. Stabilizer only slows the chemical breakdown; draining the carburetor is the single best way to avoid gummed-up jets.
