Proper Installation Matters

This gasket is designed to be placed directly on the carburetor body, underneath the main metering diaphragm. Incorrect placement (i.e., above the diaphragm) can cause poor carburetor performance, tuning issues, increased wear, and potential fuel pump leaks.

To ensure optimal sealing and ease of removal during future maintenance, we recommend applying a light coat of mineral oil (e.g., Marvel Mystery Oil) to the gasket before installation.


Maintenance Tip:

While this gasket can often be reused during carburetor rebuilds, for best results and peak performance, we recommend replacing it every 3–5 races along with the main metering diaphragm.
