Help on Quadrajet Divorced Choke

So I got this old truck on the cheap and am trying to fix a few things and sell it. One thing that is missing is the choke. It seems that there were Qjets made with heat risers and also some a thermostatic coil...both referred to as divorced chokes? Both attached to the intake manifold?

Attached is a pic of what I am dealing with (purple line indicates missing linkage). It appears there is a housing, or part of a housing with some missing parts and a missing linkage rod. What do I need to rebuild this? I know there are electric choke conversions but they are like $50. And like I said I want to keep costs down because I intend to sell this truck for profit.

Also the truck does not seem to fast idle. I am not sure if that is a separate issue or is directly related to the missing choke. Any help is greatly appreciated!

Divorced choke = choke coil mounted somewhere other than on the carb. Hot air or electric integral choke = choke coil mounted to the carb.

The divorced choke coil and housing fits where the red circle is located. I believe the secondary lock out arm is on backwards (red arrow).



The divorced choke set-up looks similar to the one below, it's a 2-barrel and details differ a bit:

Dang Cobalt! Yes I checked my pre-disassembly photos and that lock out arm is installed incorrectly.

So if the area you circled is for the divorced choke, then what is that "thing" on the left that I thought was the choke?

Cobalt327, good description and pic. SS, you can pic up the Chevy-style coils and links at most parts stores. If not local, any resto house.

That "thing" on the left is the remnants of an EGR valve someone disabled at some point.
