Troubleshooting & FAQ
How do I know if this gasket will fit my BRP engine?
This gasket is a direct replacement for BRP part numbers 331499 and 338878. The most reliable way to confirm fitment is to check the part number specified in your engine's service manual or on the original part itself.
What are the signs of a failing float bowl gasket?
Common symptoms include visible fuel leaks or stains around the carburetor, a persistent gasoline smell, poor or rough engine idling, stalling, or difficulty starting. A compromised gasket allows excess air in or fuel out, disrupting the engine's fuel-air mixture.
Should I use sealant with this gasket?
In most cases, this gasket is designed to be installed dry. Applying sealant can sometimes interfere with a proper seal or cause excess material to squeeze into the carburetor's internal passages. Always follow the specific recommendations in your engine's service manual.
When should this gasket be replaced?
The gasket should be replaced any time the float bowl is removed for cleaning, jetting, or other service. Gaskets compress and harden with use and may not reseal correctly if reused, leading to potential leaks.
