ABSTRACT:
The ignition timing system of the present invention comprises a rotor plate having a plurality of pin receiving holes therein. Several pins may be positioned in the desired holes on the upper surface of the rotor plate. The rotor plate rotates in unison with the camshaft of the engine, and the pins pass through optical sensors which are capable of creating an electrical trigger signal each time a pin passes thereby. Electrical circuitry is connected to the optical sensors for converting the trigger signals into firing signals delivered to the cylinders of the engine. The electrical circuitry includes screw adjustments for adjusting the rpms at which the spark advance is changed. The location of the pins on the rotor plate determines the amount of spark advance which occurs at each level.
