Our carburetor gasket kit for 13 HP Honda GX390 engines comes with three gaskets and a spacer/insulator. These may be used on numerous go-karts, power washers, and lawn& garden utility engines. This gasket kit may also fit carburetors for the Honda GX340 11 HP engine. The three gaskets in this kit are all compatible with the spacer/insulator but are cut for the three most common carburetor base configurations for13 HP Honda GX390 engines .

The spacer/insulator is made of high-temperature phenolic plastic and is impervious to high manifold temperatures. This insulates and reduces the heat flowing into the carburetor to both keep it cooler and to allow a denser fuel mixture that produces more horsepower.
