I am no carb expert, but the terminals that you describe sound like connections for an electric-thermal choke pull off. I have this on several of my other cars from GM and FMC. There is a disc in the housing that heats the choke spring, activating choke opening during warm up. Imperials from the '60s usually had a spring mounted in the intake manifold that heated up and pulled a lever to open the choke. You should be able to make this work.

Hi everyone!
I'm rebuilding a Carter 4327 to go on the '67 Imperial 440 I have in my 300L. Any carb experts out there?
In the FSM, it identifies that carb application as a non-CAP, High Performance. A-OK with me. The carb has a choke set-up that is not shown in the FSM - at least I don't think so. (the FSM refers only to a "well type" choke - that's the kind that hides in the intake manifold, right?) This choke is a disc, just a bit smaller than a snuff tin, mounted on the carb right where the vacuum choke pull off would be. It has the thermo-coil in the housing and also a piston that seems to act as the vacuum choke pull-off.
The rebuild kit shows this choke set-up on the diagram - still A-OK. One question is - what are the two electrical terminals on the outside of this choke housing, disc looking thing for? Do they need to be connected to anything for the choke to operate correctly? Or, are they test leads for the mechanic to check choke operation?
Also, I am missing the choke connector rod (I might find one in the basement) and I am not sure where it attaches. To the slotted bracket or to the hole on the choke rod?
Lastly, I have no springs pulling on any of the carb linkage (except throttle rod and throttle return). In trying to figure out the operation of the primaries & secondaries, it seems that there should be something pulling on something else.
Wow! Way too detailed - and yet way too vague!! Is there a Carter doctor in the house? Or anyone that has a rebuild book that can advise of the way chokes and springs work?
I know this is a tough one!!! Thanks,
Dan Richardson
