I have bought and installed a rebuilt kit for my carb and nothing. Just wondering if there is anything else i can try. Oh my engine does run really hot but never overheats. thanks
Connecting the choke wire back to the choke should make the light go out. All that's wrong w/your choke is the fast idle is out of adjustment. The manual (links below) gives instructions on how to adjust it. There's no reason not to use the choke, but if you want the light off and do not want the choke to work as it was intended to, hook the wire up to the choke and adjust the choke to be wide open all the time.

If hooking the choke wire to the choke doesn't put the choke light out, the first thing to check is for a blown fuse- that can cause the choke light to come on and is the easiest thing to check.

The alternator malfunctioning will also cause the choke light to come on. Funny thing, the choke being bad will not make the choke light come on, but that's another story.

Something to check for the excessive pumping of the gas to get it to start is the accelerator pump. It's easy to check: With the engine OFF, look into the primary side of the carb (side w/the choke blades) using a flashlight and work the throttle open and closed. Every time you open the throttle there should be two streams of gas coming from the accelerator pump discharge nozzles. The streams should be nice, full shots like from a small squirt gun, and not bubbly or frothy/drippy, if you follow me. And the streams should come just as soon as the throttle blades start to open.

The Edelbrock owner’s manual is here. With the info from it and from Edelbrock Performer Series Carburetor- Complete Guide to Set-Up, Tuning, and Performance Jetting, you should be able to tackle most any carb related problem.
