Troubleshooting & FAQ

How do I know if this gasket kit fits my Mercury engine?

This kit is for specific Mercury/Mariner models, including 7.5–50 HP 2-stroke engines. Review the "Engine & Model Compatibility" table and cross-reference your engine model and year. Always compare the product images to your old gaskets before installation.

Does this kit include everything for a full carburetor rebuild?

This is a gasket kit containing essential seals for servicing the carburetor. It may not be a complete rebuild kit, which often includes jets, floats, and other hardware. The kit notes the use of a 7295 needle, but it is not confirmed if the needle is included. Please review the "What’s in the Box" section and photos.

What are the signs my carburetor needs new gaskets?

Common signs of failing gaskets include fuel leaks, rough idling, stalling, hard starting, or poor engine performance. Visually inspect old gaskets for cracks, brittleness, or excessive compression.

Is any sealant needed for these gaskets?

Generally, carburetor gaskets are installed dry and do not require additional sealants. Using sealant can interfere with proper sealing or clog small fuel passages. Always consult your engine's service manual for specific instructions.
