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. When the operating lever is rotated in one of the directions, the lever engages with the speed control lever to rotate the speed control lever to a second position for providing a high engine speed for a high frequency output from the generator.
