Troubleshooting & FAQ

How do I confirm this fits my engine?
This kit is designed for Mercury/Mariner outboards with WME series carburetors. Please check the "Compatible Engine Models" section and verify your carburetor model number is listed. Cross-referencing your old part number with the numbers in the "Part Number Cross-Reference" table is the best way to ensure a match.

Why are there extra parts in the kit after I finished the rebuild?
This is a comprehensive kit designed to service a wide range of WME carburetor models. Because of the variations between carburetor models (e.g., WME-11 vs. WME-45), the kit includes multiple gaskets and components. You will have leftover parts, which is normal.

What are the signs that my carburetor needs a rebuild?
Common symptoms include difficulty starting, rough idling, engine stalling at low speeds, poor acceleration, black smoke from the exhaust, and fuel leakage. If you experience these issues, a carburetor rebuild is often a necessary service.
