Can someone explain to me how an electic choke works - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey guys thinking about getting an Edelbrock 1406 with an electric choke? I was just wondering how that really works, would my manifold need an EGR valve or what to run the electrical choke?
thanks
John

you dont need egr, you hvae a pre 73 truck, no egr on vehicles prior to 73

electric choke recieves 12 volts from ign switch and the power heats up the heat coil inside the housing and that unwinds it and spins the shaft in there and the rod connected to it runs up to tha choke air valve and slowly opens it, electri choke are quicker and very adjustable and simple to connect and very reliable/.
if you take one off the carb then youll see exactly how it works

good luck

From an end user standpoint, the main difference between an elctric choke and a regular one is the elctric one goes from fully closed to fully open in a set amount of time. It takes X minutes, which is adjustable on most. The regular thermostatic choke is dependeant on actual temperature, as it uses engine heat to unwind the bi-metal coil. On cold days, my regular choke can take 15 minutes to go fully open, where an electric choke would be however many minutes I set it to every time.

in wihich i consider a plus, cuz them damn bi-metal spring chokes take forever to unwind,...
