electric choke conversion

[rowingone]

I'm considering converting my manual choke to automatic . . how does an electric choke differ from a hot air choke in terms of ease of installation and operation? Thanks to all who have helped me . . . as I get closer to completion I have more and more questions!!! Oh and its a holley carb.

There are two spade connections on the electric choke housing - one is marked (+) and takes ignition-switched full 12 volts (get it from the ignition switch side of the ballast resistor, NOT from the coil (+) terminal or coil side of the resistor), and the (-) spade gets a ground wire to a convenient screw on the carb or under a carb attaching nut. Without power, the choke is closed; when you turn on the ignition, the bi-metallic coil in the housing heats up and gradually opens the choke; you adjust the rate at which it opens by turning the housing cover. I've used Holleys with electric chokes on many project cars, never had a problem with any of them.

I put an electric choke on my car about 5-6 years ago. No problems. A few years ago I pulled a GM electric choke of a car in a junk yard, but I never got around to installing it. The aftermarket choke has a control block that is bolted to my intake. The GM unit doesn't use one.
