ABSTRACT:
A rotating speed control apparatus for controlling the rotating speed of an internal combustion engine includes: an ignition circuit of a capacitive discharge ignition (CDI) system; an overspeed preventing circuit having a rotating speed detecting circuit for reducing the rotating speed of the engine to a restricted value in response to an overspeed condition; and a cut-off circuit which temporarily inhibits the control of the engine speed by way of an overspeed prevention inhibiting operation and which is automatically returned to a condition in which it can control the engine speed during restarting of the engine after a stop of the engine. The overspeed preventing circuit is cut off by turning on the cut-off circuit when the engine is driven, so that the overspeed preventing function is inhibited. This cut-off circuit is automatically returned to its off-state when restarting the engine after a stop of the engine, thereby allowing an overspeed of the engine to be prevented.
