Choke - Electric Assist: Operation

Choke thermostatic coil spring reacts to engine temperature. In addition, an electric heating element located next to bi-metallic spring inside choke well assists engine heat to shorten choke "on-time". The single-stage electric assist choke gives rapid choke openings at temperatures above 60°F (16°C), and slower choke openings below this temperature. A wire from choke heater is connected to an electrical control switch mounted on top of intake manifold. Above 60°F (16°C), control switch energizes choke heater.
