edelbrock too rich with choke on

This is probably a real simple thing, but I've never had any experience with an electric choke. I just installed an electric choke onto my 750 edelbrock. With the choke closed it runs really rich. I've tried turning the black choke cylinder all the way to the lean side but it has no effect. Any suggestions?

When you rotate the choke cover toward the "lean" direction, does the choke butterfly eventually open?

Usually, turning it (when cold) just until the butterfly is about 3/16 to 1/4" from the closed position is about right.

When you have power to it, does it eventually fully open?
When you have power to it, does it close even more? Seen this a very few times when the coil spring was installed backwards when built.

Well Jmark, I put your tests to work and in doing so, eventually figured out the problem. I had swapped the electric choke from a 600 cfm edelbrock to a 750 that originally had a manual choke. I only swapped the electric choke canister over. I didn't realize that the fast idle linkage was also different. With the electric choke canister and the manual choke fast idle linkage, the choke was never fully opening.

It seems like a lot of work to swap the fast idle linkage so I guess I'll just go back to the manual choke. Thanks for the help - I owe you a beer.

Glad you atleast figured it out! Too bad it's not an easy fix. I really like the electric chokes.
