Troubleshooting & FAQ
How do I know if this kit fits my specific engine?
This kit is designed for Mercury/Mariner outboards with WME series carburetors. The best way to confirm fitment is to identify the model number stamped on your carburetor (e.g., "WME-11") and check it against the compatibility list on this page.
Why are there extra parts in the kit after my rebuild?
This kit is designed to service dozens of different WME carburetor models. It includes a variety of gaskets and small components to cover these variations. You will only use the parts that match your specific carburetor, and the rest can be discarded.
What are common signs that my carburetor needs to be rebuilt?
Symptoms of a failing carburetor include difficulty starting, rough idling, stalling at low speeds, engine hesitation or sputtering during acceleration, and black smoke from the exhaust, which indicates a rich fuel mixture.
Can I clean my carburetor without a rebuild kit?
While you can clean a carburetor's jets and passages, a full rebuild is recommended. Over time, gaskets become brittle and swell, and inlet valves wear out, leading to leaks and improper fuel regulation that cleaning alone cannot fix.
