Complete replacement carburetor with lever and built in Fuel Filter. Fits many 5.5-6.5 HP General Purpose 4-Stroke Engines, used on lawn mower, power generator, go-karts and select dirtbikes/Motorcycles. This version includes a Fuel Shut Off Switch with an integrated fuel filter below it. This is a handy feature to help keep your carburetor clean of debris. However, this carburetor will not fit all models as your vehicle's/equipment's design may not have enough room for the filter to fit. Be sure to check your clearances before ordering. We offer both versions with and without the built-in fuel filter.
