Help identifying carb part

[ianmattdodge]

I am trying to figure out what this canister part is that comes in contact with the throttle linkage. what is it called and what does it do. I turned it all the way clockwise on my truck and it raised the throttle a bit. Is this bad. i was trying to turn the carb a bit for our cold weather coming in Colorado.

It looks like you've got an aftermarket bolt on EFI but I don't know anything about adjusting them.

I believe it's an idle solenoid. It's controlled by ecu but there is some adjustment on the threaded mounting bracket.

I dont believe there is an ecu. and no fuel injection. Its carbed. This is an 1985 dodge d100 truck with a 318. This picture is actually one I got offline but its the same exact engine and mechanism. I am looking all over the internet to find what this part is and does. This is my sons truck and now that winter is here its running really rich and flooding out. Any other thoughts on this part?

Disregard my first post, Rustycowl's right it's an idle stop solenoid. It's function is to increase the idle speed when the AC is turned on.

I have an 86. It has a computer. It is kind of hidden behind the battery. It was what they called a feedback carb. I don't KNOW you have one, but they had "Lean Burn" computers as far back as 76.
Possibly, somebody converted it back to just electronic ignition, and eliminated the computer.

Looks like a choke control valve to me. IF it is hooked to the linkage that operates the choke butterfly, it's an electronic choke valve. If it is connected to a linkage that goes to the throttle, it IS a idle control for the AC or something.
