This is a genuine OEM replacement float for use in a long list of snow throwers and lawn mowers. A float is a relay component of an engine's fuel tank. As its name suggests, it floats on top of the fuel in the tank, and as the liquid rises, it pushes the float upwards, blocking the float needle to prevent more fuel from entering the chamber. This helps prevent too much fuel from combusting, guaranteeing a balance of air and gasoline in the carburetor. Carburetor floats are generally designed to last the full lifetime of an engine, but they can occasionally wear out and need replacing. When this happens, the carburetor may begin to flood, causing fuel to leak from the engine. This poses a safety hazard and should be repaired as soon as possible. You will need a set of wrenches, socket wrenches, a screwdriver, and pliers to make this repair. This part is compatible with Cub Cadet, MTD, Craftsman, Toro, Tecumseh, and Lawn Boy snow throwers and lawn mowers and comes sourced from the original manufacturer. This is a high-quality replacement part and does not ship with additional hardware.
