    Abstract: A speed control lever is provided to position a throttle valve at a first position for providing a low engine speed for a low frequency output from a generator driven by the engine, and an operating lever is rotatably provided. A spring is provided to urge the operating lever in opposite directions with respect to a neutral position.
