Abstract
A rotational speed control system for an engine includes controls for determining whether the throttle is closed beyond a predetermined position, whether the engine is mechanically loaded, and whether the engine rotational speed exceeds a predetermined speed. A control delays the ignition timing of the engine when the throttle is closed beyond the predetermined position, the engine is not mechanically loaded, and the rotational speed exceeds the predetermined speed.
