Frequently Asked Questions

Will a dirty filter hurt the carburetor?

Yes. A clogged filter richens the mixture and lets grit reach the carb and bores, so keep it fresh.

How do I check if my air filter is dirty?

Pull the element and hold it up to the light. If it is dark, packed with dust, or you cannot see light through it, replace it. A clogged filter richens the mixture and dulls throttle response.

Can I clean and reuse a paper element?

No - blowing out or oiling a paper filter tears it or lets grit through. Replace it rather than clean it.
