Hi guys, I am going to be installing an electric choke on my Holley 650 double pumper. I installed one a couple of years ago in a different car and it didn't go great. It never quite worked the way is should. It would open the carb too quick and the car wouldn't be completely warmed up and it would stall. I would like to get some detailed instructions. The Holley instructions aren't that great. If you could also give me any do's and don't I would appreciate it. Thanks in advance.

As far as it opening to quick,thats just an adjustment on the bi-metallic spring housing,leaner opens quicker,richer takes longer to open

Bending the choke plate linkage changes how much the choke opens at start up and when the car is fully warmed up. It is kind of tricky adjusting anything because when you adjust one thing it changes something else. Try to get the fast idle right first and then dial in the bi-metallic element.
