This is a fuel cut-off value that is used in over 150 different small gasoline-powered engines. Those devices that have this value include power vacuums, leaf blowers, pressure washers, and generators. The fuel cut-off valve is a safety feature that sits on the bottom of the fuel tank. In situations where the engine must be cleared of gasoline, this valve is very useful. It allows the gasoline in the fuel line to continue to the carburetor and to be combusted in the cylinder. Once the engine block is drained of gasoline, no further ignition of fuel is possible until the cut-off is reactivated. Although it is out of the way of casual contact, the cut-off can be bumped and damaged by contact with other tools, hoses, or debris. Also, since it is a narrow passage through which gasoline passes, it is possible for contaminants to jam the flow and create a blockage. If the tank is full of gasoline and the carburetor is functioning normally, an engine that won't offer to start at all may be the victim of a faulty cut-off fuel valve. This OEM genuine replacement is compatible with Toro and Briggs and Stratton engines.
