ABSTRACT:
A spark and throttle control arrangement for an internal combustion engine for altering the spark advance angle in response to the position of the throttle valve. The mechanism includes a throttle control lever and a spark control lever that are pivotally supported about independent pivot axes and a cam and follower arrangement operative between them so as to effect more rapid pivotal movement of the spark control lever than that of the throttle control lever during a phase of the initial rotation of the throttle control lever. Embodiments are disclosed so that the spark advance curve may be tailored to that of the engine by providing different rates of advance during different degrees of throttle opening and/or including a dwell.
