A/C question
I know my a/c is not original, but is from that era. Can anyone tell me what would have been used or what can be added now to kick the idle up when running the a/c. In the past, I've adjusted the idle ever so slightly to compensate. Was wondering what would be more correct.

Ford used a solenoid like this one, wired into the compressor clutch circuit. You will have to find or make a bracket to mount it if your carburetor doesn't have one already.

Thanks to both for the info.
So went and dug out the original 2bbl carb that was on my truck when I bought it. Low and behold, there's the bracket. Never gave it any thought. Doh! Looks like the bracket for the holley was there all along too. Now I know what to look for. Thanks for the diagram.

What actuates it? Nothing connected to this one.

The spring holds the plunger outward at a certain distance and when the throttle linkage hits the plunger it takes a couple of seconds for it to depress during which it keeps the butterfly valves slightly open keeping the engine from stalling. The distance is adjusted using the threaded end and lock nut.

So the one in my second picture would solve problems with sudden deceleration. For the a/c would it need to be vacuum actuated? Or would only 2 second stoplights allowed? Or readjusted for winter/summer?

For the A/C system it is usually tied to the compressor clutch engaging. Since the compressor takes some engine power to run it when it is engaged it's not uncommon to have an electrically activated solenoid like in Crop Dusters picture.

That's the bracket you need for what you're trying to do. A dashpot isn't going to cut it. Like Chad and crop Duster said, you need to bump up the idle when the A/C is on, so it has to be tied into that circuit.

So, similar then to my first picture. One to help with sudden stop/decel, and a separate one for A/C? ND states that original for A/C wouldn't have been electric. Don't see a second one on my Lincoln though. And I believe that carb is original to both me and the car (51,000 miles actual).

That's what I'm figgering. Whether original was electric or not, probably what I will go for.
Always looking to learn though.

And, no Lincoln had a 2100 series 2V, all were 4V's.
