PROBLEM TO BE SOLVED: To prevent engine speed from lowering below an idle target speed even when the engine speed is higher than the engine speed in a transition running state and a throttle valve opening is near an idle opening in a case where a throttle lever is early released or the like. SOLUTION: When the engine speed is higher than the engine speed in the transition running state and the opening of the throttle valve 35 is near the idle opening in the case where the throttle lever is early released or the like, an ignition timing of an ignition plug 38 is controlled so as to be advanced by an engine control unit 59.
