I think it has arrows on the cap. You can just move it. Little one way then the other and see what works best. Mark it before you start with a paint marker so you can always return to that setting a line across the plastic and metal should do the trick.

Also remeber edelbrock will walk you thru the setup of the choke over the phone for free. Some of the guys there are pretty smart and can help you get it workedout. Also the instructions on how to adjust the choke are on the net for download.

With the engine OFF and the key OFF, run a jumper wire to the choke from the battery positive terminal. Block or hold the throttle open a little bit so the fast idle cam isn't under the pressure of the throttle return spring. The choke flap should open wide open in a few minutes if the choke heater is good. Don't worry- doing this will not burn anything out or hurt the carb or choke. Just don't short the jumper wire against a ground and you'll be fine. Be sure the choke has a good ground, also. If it doesn't it will not open.

What puzzles me is you saying it idles down when the choke is disconnected. Does that mean the choke is fully open when the engine is hot and the choke disconnected?

But the choke will not open fully, allowing the engine to idle down off the fast idle cam when the choke is connected to power?

cobalt327, the way I understand what he said is the the choke plate only has a 1/4 gap. It was idling about 2000-2500 rpms for 15 minutes. He jump in and took a ride for about five minutes and when he got back it was idling about 1500-1800 rpms. When he diconnects the wire and drives it the idle will drop to 500-700 rpms. The choke is still fully engaged after warm up. May be he doesn't have a ground wire hooked up. Or maybe he needs to loosen the 3 screws and adjust the choke cap until the choke plate opens.

If that's the case, with the engine fully warmed up, rotate the choke cover (the round black plastic part that has the electrical terminals on it) counter clockwise until the choke is fully open. This will be a rough setting, the cover will very likely still need fine tuning.

There are notches on the choke housing and cover to use as a guide (circled on image below), keep track of the setting by using them. In fact, the notches should be way off if the choke cover is out of adjustment. Putting the cover back to between "RICH" and "LEAN" marks should be the default setting unless something is amiss w/the choke coil.
