I have a Holley 4bbl double pumper with electric choke that stays way too wide open..

So was wondering if i could get some help with this one its a holley electric choke i think like 4180 carb not positive though anyways I hooked it up to the windsheild wiper motor which i heard should be fine for an 85 gt because its a key on source and its getting a little over 10 volts which should be enough i think but when started at first it was closed but opens wide after a few seconds now i dont know much about them but i think i heard it could be either heat operated or maybe the constant flow of power to it when the key is turned maybe opens it I dont know but if anyone has any ideas please help me out its much appreciated thanks

If its wide open after only a few seconds, it's likely that the electric choke needs to be adjusted.

The electric choke is easiest adjusted when the car is at ambient temperature. Just a light nudge off idle position, and adjust the choke to fully closed. If the windshield wiper or whatever its hooked to is powered up when the key is on, then yes, turn the key off. Now the adjustment wont be just til its closed. It will likely need a little more than that. I'd adjust to fully closed at ambient temp, then give it a slight amount more. Tighten it up, reattach the power wire, and start the engine. You'll be able to tell if you need a little more or less choke, and adjust accordingly. I'd suggest locating a better power source than the windshield wiper circuit.

This is all assuming that the choke will turn in the housing when the 3 screws are loosened. If it will not move, you must find out why. Theres not a lot that can go wrong with that component.

Anything that can deliver power when the ignition is in the RUN position.
