This item is a replacement gasket identified as Zenoah K207514120, made to fit the engine codes listed in the product name. Its purpose is to maintain a reliable seal between carburetor mating surfaces and prevent fuel or air leaks that can affect running quality.
Fitment is restricted to the model codes shown: G230-290RC, G260PU, G231-260PUH, and G231-290PUM. Always verify the code on your carburetor prior to purchase to ensure compatibility; other engines are excluded.
To install, detach the carburetor from the engine, remove old gasket remnants, degrease the faces with an appropriate solvent, position the new gasket flat, and reassemble using the original screw arrangement and torque recommendations. Avoid excessive tightening to prevent deformation.
Maintenance note: replacing degraded gaskets prevents vacuum leaks that can skew jetting and idle adjustments. Swap the gasket when you detect seepage, visible wear, or persistent running issues after other tuning steps. Stock spare gaskets for routine engine servicing and rebuilds.
