This Carburetor Repair Kit 26-1383 includes all components required to repair a carburetor. Included are O-rings, gaskets, jets, needle, mixture screw, float bowl screws, float valve needle and seat—all in the original equipment manufacturer's (OEM) jet sizes. NBR rubber is utilized for O-rings and gaskets due to its strong resistance to ethanol-blended fuel. Kits for applications that use paper float bowl gaskets are instead equipped with superior High Performance Interface Gasket material. Note that components in this kit are based off of US models; therefore, caution should be exercised when utilizing them on non US models. Intended for off road use only.
