Troubleshooting & FAQ

How do I know if this kit fits my carburetor?

This kit is specifically designed for Holley 4-barrel carburetors used on Mercury/Mercruiser Ford V8 engines (302 & 351 CID) from 1970–1974. Check the compatibility table to confirm your engine model and year. It is crucial to also verify your original carburetor's model number, such as #C9FF9510E, #D2JL9510C, or #D2JL9510E, as noted in the compatibility list.

What are signs my carburetor needs a rebuild?

Common symptoms indicating a need for a rebuild include rough idling, frequent stalling, hesitation or poor acceleration, visible fuel leaks from the carburetor body, or excessive black smoke from the exhaust. These issues are often caused by worn gaskets, clogged jets, or faulty seals that this kit can replace.

What is the benefit of adjustable needles & seats?

Adjustable needles and seats allow for fine-tuning of the fuel level inside the carburetor bowl. This enables precise calibration to optimize engine performance, smooth out idling, and improve fuel efficiency based on your specific operating conditions and engine setup.
