Carburetor Assembly
The needle valve inside the carburetor has failed to seat properly, likely due to ethanol-induced corrosion or debris at the seal interface. This prevents the float from stopping fuel flow once the bowl is full, leading to an overflow condition where fuel leaks from the intake or the bowl nut. Replacing the entire assembly ensures a new, factory-honed seat and needle interface, which is often compromised on these specific engines.

Carburetor Service Kit
This kit contains the needle valve and the bowl gasket. Replacing the needle addresses the most common point of failure for leaks, assuming the internal metal seat in the carburetor body is still smooth and free of pitting. It restores the mechanical shut-off capability of the float system.

Carburetor Bowl Gasket
The bowl gasket provides the seal between the fuel reservoir (bowl) and the carburetor body. If the leak is occurring specifically when the unit is tilted or vibrating, the elastomer may have shrunk or become brittle, failing to maintain a seal against the hydrostatic pressure of the fuel.
