Electric Choke System

Electric Choke System utilizes a choke cap, thermostatic spring, a bi-metal temperature sensing disc (switch) and a ceramic positive temperature coefficient (PCT) heater. Choke is powered from center tap of alternator. Current is constantly supplied to switch and unit is grounded to carburetor body. At temperatures above 60°F sensing switch closes and current is supplied to ceramic heater. As heater warms, thermostatic spring pulls choke plates open in 1 1/2 minutes.
