This Carburetor Repair Kit 26-1211 comes with all the essential components needed to repair a carburetor. It includes O-rings, gaskets, jets, needle, mixture screw, float bowl screws, float valve needle and seat, all per OEM jet sizes. The O-rings and rubber gaskets are NBR, offering excellent resistance to modern ethanol blends. Where needed, paper float bowl gaskets are upgraded to more durable High Performance Interface Gasket material. Some US models may require modifications for application on non-US models, and these kits are for off-road use only.
