on the project 69 impala, there is a holley quadrajet replacement carb. it is list # r8679. It has a divorced choke, that I had hoped to convert to electric. After trying to convert it and failing I found out that there is no way to do it according to holley. I had already disassembled the choke when I found this out and had not taken any before pictures. Holley has no information to help me. Google is falling short of useful pictures. At this point I'd be glad just to get the old choke pieces back on in the right places.
Do you have photos if what you have?
Is there supposed to be a rod that goes from the wound bi-metal spring on the manifold to the lever on the choke assembly?
Also, can you convert it to a manual choke?
I would go with a manual choke, myself. There are quite a few pieces missing in the photo. Do you have all of the peices?

In reply to Cooter :
the pieces missing from the carb, are still in a plastic baggie until we figure out where it goes.
We don't have the cover for the coil that is bolted to the manifold.

Buy a Qjet. Problem solved.

In reply to Curtis :
not quite in the budget right now. we rebuilt this carb already BEFORE I took off and screwed up the choke setup (which wasn't working anyhow).

Hard to tell you how it goes together over the intrawebs, especially since I'm not able to see the pieces that you took off.

The divorced choke is pretty generic and a super-simple mechanical piece. I would suggest hitting a junkyard and buying a divorced choke coil from a car (last time I did that they didn't even charge me) and bend a piece of coat hanger to fab a linkage.
The way they work is that you adjust the choke by bending the linkage rod. I've done this many times and it works perfectly. Heck, I even did it with some 14ga copper electrical wire once
The cover for the coil is not necessary, but helpful. It traps heat. If it's off and exposed to ambient underhood temps, it may not fully heat up and "come off" the whole way. You might be able to adjust it such that it works within the range of temps without the cover.
Adjusting it is pretty easy. When its cold, you want it to snap shut but not be tight. It needs to float open a bit after it starts and gets airflow. That will get you close and you can fine tune it from there.

In reply to Brian :
Everything on the bottom attaches to the throttle shaft. The rod attaches to the no-metal spring .

Tried to, it got very grainy. I found a pic on ebay of it, just trying to confirm it's going back together correctly.

we're goofy. There's a broken 3310 sitting on my buddies desk at the shop. That shows how the bottom setup goes. The 3310 doesn't have any choke setup on it.
The rod connects the bimetal to the choke lever.
The two levers and the spring go on the throttle shaft for fast idle.
You are only missing the cover for the bimetal spring.
