Troubleshooting & FAQ
How do I know if this kit fits my carburetor?
This kit is specifically for early MerCruiser 3.9 and 110 inline engines that use a side bowl carburetor corresponding to OEM part number 40470. The most reliable method is to cross-reference the part number stamped on your old carburetor or in your service manual.
What are common signs that my carburetor needs a rebuild?
Symptoms include hard starting, rough idling, stalling, poor acceleration, black smoke from the exhaust (running rich), or visible fuel leaks. A rebuild with a fresh kit can restore proper fuel and air mixture.
Is this kit for a side bowl or center bowl carburetor?
This service kit is for a side bowl carburetor configuration, as noted in the technical specifications. It will not work for center bowl models.
How often should a marine carburetor be serviced?
Service intervals depend on usage, fuel quality, and storage conditions. It's good practice to rebuild a carburetor every few hundred hours or if the engine exhibits symptoms of fuel system problems. Gaskets can dry out over time, especially with ethanol-blended fuels.
