Abstract
An engine including a fuel tank, a carburetor, a speed control lever, and a transport valve. The carburetor includes a throttle valve movable between a first throttle position and a second throttle position. The speed control lever is coupled to the throttle valve and is movable between a first position corresponding to the first throttle position and a second position corresponding to the second throttle position. The transport valve is fluidly coupled between the fuel tank and the carburetor, and includes a valve element moveable between an open valve position allowing fuel flow between the fuel tank and the carburetor, and a closed valve position preventing fuel flow between the fuel tank and the carburetor. Movement of the speed control lever to the second position moves the valve element to the closed valve position to stop fluid flow between the fuel tank and the carburetor.
