摘要： A rope for actuating a recoil starter is trained about a movable pulley outside a main body of the recoil starter, and the movable pulley is rotatably supported by a swing arm or a handle. By moving the swing arm in swinging movement or pulling the handle, the movable pulley can be moved to thereby pull the rope out of the main body of the recoil starter to start the engine. By virtue of the action of the movable pulley, the distance covered by the movement of the swing arm or the handle is smaller than the length of the portion of the rope paid out of the main body of the recoil starter to actuate the recoil starter. At least one further pulley may be provided for guiding the rope in its movement, and a manually operated handle may be additionally attached to the rope. Pulling of the rope automatically makes it possible to actuate an auxiliary engine starting means.
