Electric Choke on Carter AFB
Operated the same as the factory bimetallic type. To set choke, pump gas once. Choke and fast idle should set with cold engine. Tap throttle once after starting to unload choke. After the ignition has been on (and the engine has warmed) for 3 or 4 minutes, choke should hold off. Many OEM's ran choke heat wire through an oil pressure switch so the coil wouldn't heat unless the engine was actually running.
