Abstract
A breakerless ignition distributor equipped with a pair of centrifugally responsive spark retarding discs sandwiched between a pair of bearing members all held assembled to the distributor shaft by a readily adjusted clutch. Centrifugally responsive balls held captive in sets of diverging slots in the two discs are urged by calibrated springs to their inner or retracted position. The centrifugally actuated disc has a ring of peripheral openings rotating across a light beam to activate a solid state ignition circuit and is effective to retard the spark during engine starting and to advance the spark thereafter. The distributor is quickly convertible for operation either clockwise or counterclockwise.
