An engine speed limiter includes a computing means for computing a value that is functionally related to the time between successive ignition pulses and for outputting a speed signal representative thereof. The speed limiter also includes generating means for generating a reference signal that is functionally related to the desired maximum limit speed. A comparison means compares the speed signal with the reference signal and generates a limit signal if the result of the comparison indicates that the actual engine speed is about equal to or greater than the desired maximum limit speed. The limit signal is used to interrupt engine ignition to thereby limit engine speed.
