1. In a event timing arrangement for an internal combustion engine having an engine output shaft, a pair of relatively moveable components defining a combustion chamber, at least one of said components being operably connected to said engine output shaft for driving said engine output shaft, and timing means for effecting a timed event for said engine at a predetermined angular position of said engine output shaft, the improvement comprising indicating means driven in timed relation to said engine output shaft, a signal generating means fixed relative to one of said engine components and juxtaposed to said indicating means for generating a basic timing signal in response to the passage of said indicating means past said signal generating means and an adjusting circuit for adjusting the output of said signal generating means in order to vary the timing of said signal to adjust for discrepancies in the relative locations of said indicating means and said signal generating means for initiating the operation of said timing means at a precise engine output shaft angle.
