Description
Overview:
This genuine Honda carburettor gasket (part no. 16221-ZF6-800) seals the joint between the carburettor and intake on GX390 petrol engines for reliable, leak-free running. Made from durable, fuel‐resistant composite gasket material, it helps maintain correct vacuum, stable idle, and clean throttle response by preventing unmetered air ingress and fuel seepage. The precise cut-out matches the GX390 intake port and stud pattern for an accurate fit and consistent performance. Commonly found on generators, pumps, pressure washers, plate compactors and other plant using Honda industrial engines, it is a straightforward service replacement when removing or refitting the carburettor. Suitable for professional workshops and DIY users alike, and directly compatible with GX390-powered equipment such as the GX390 and EC5000 generator.
