ABSTRACT:
Two embodiments of ignition timing mechanism wherein a timing curve is generated in response to the position of the throttle valve. In each embodiment the timing is advanced on progressive opening of the throttle valve until a predetermined maximum advance is obtained at a position less than wide-open throttle. The timing is then retarded from the maximum advanced position as the throttle valve is continued to open to its wide-open throttle position. In each embodiment the timing is retarded beyond the maximum advanced position to a predetermined advanced position prior to fully wide-open throttle position and this advance is held during the remainder of opening of the throttle valve.
