Dual Point Distributor

Selection of retarded or advanced point set is made as follows. During idle, accelerator switch is ON and retard point set operates. During acceleration and high-speed running, accelerator switch is OFF and advance point set operates. When decelerating, speed switch and accelerator switch are ON, which operates retard point set. 1800 models and 616 California models with automatic transmission, also incorporate a vacuum switch to control retard point set. Whenever manifold vacuum rises to 2.7 in. Hg. or more, vacuum switch is turned ON which operates retard point set.
