Frequently Asked Questions

What does this set cover?

It seals the carburetor joints and base. Match the exact contents to your carburetor in the listing photos before ordering.

How do I know the carburetor gaskets are leaking?

A hunting idle that changes when you spray carb cleaner near the base is an air leak at the gasket, and fuel weeping from a joint is a failed seal. Both mean fresh gaskets.

How do I make sure it seals?

Clean both faces fully and check the carb flange is not warped, then torque the base evenly - a warped flange leaks past any gasket.
