The solenoid valve provided inside the starting aid device is controlled by a control unit equipped by a control circuit board and is driven by power of the battery so as to open/close a fuel inlet hole. At the time of starting the engine, the control unit controls opening/closing the solenoid valve at an appropriate timing, so that the fuel is directly inlet to the interior of the crank chamber.
