Holley Electric Choke

[jes72mustang]

I have been having problems with the electric choke on my holley 750 double pumper. It seems to work correctly when starting but then even after the engine in warm and I start driving it will kick in again.

in other words I turn the key, press the gas to set the choke, choke closes. I start car, allow it to warm up, choke opens. I start driving and get into the gas and the choke closes again. At that point I have to shift into "N" or Park hit the gas again to get the choke to open back up.

I have it adjusted as lean as it will go now, which makes starting very difficult. but it doesn't effect driving conditions too bad.

Any ideas or suggestions?

Should I just convert it to manual choke?

The Holley electric choke is very simple. Basically there is a bi-metallic spring, which unwinds a bit as its heated. There is a tiny heater in the housing that warms the choke. This warming action duplicates the warming of the engine.

So.....make sure there is a positive 12 volts going into the choke wire. Do NOT use the ignition coil's positive wire. Usually conventional ignitions have only 9 volts going to the coil, not 12. Nine volts will not keep the choke warm enough.

Otherwise, its either the heater or the spring. Holley sells an electric choke kit with all the replacement parts.
