ABSTRACT:
Disclosed herein is an internal combustion engine including a mechanism for providing a potential capable of producing a spark when applied to a spark plug, first and second trigger means respectively and selectively operable for applying the potential to the spark plug to produce a spark at a normal timing relative to top dead center and at a retarded timing relative to top dead center, and a switch connected to the first trigger means and operable in response to engine rotation above a given speed for interrupting the operation of the first trigger means so as to change the timing of sparking operation from the normal timing to the retarded timing.
