YesIs it a idle solenoid hooked to the A/c clutch wiring? Kicks up the idle when the A/C is on.
I’m thinking it’s to increase idle speed when ac on
haven’t traced the wire but it is a blue wire so it may be from ac somewhere either control or compressorIs it a idle solenoid hooked to the A/c clutch wiring? Kicks up the idle when the A/C is on.

You're thinking incorrectly. See posts #2 and #4.
So the solenoid is what sets the idle? You don’t use the idle screw on the carb?You're thinking incorrectly. See posts #2 and #4.
I'll ask before looking it up, is the idle speed jacked up on a a/c car and the solenoid prevents dieseling by disengaging and causing the idle to go slower?You're thinking incorrectly. See posts #2 and #4.
Oh i see said the blind man. That’s how it works..I was thinking wrong thanksI'll ask before looking it up, is the idle speed jacked up on a a/c car and the solenoid prevents dieseling by disengaging and causing the idle to go slower?

Thanks I may do thatTo repeat, this was a "smog" device. It was to set idle speed and intended to close the carb at shutdown to try and reduce dieselling. My 70 440-6 had one, and the purpose of the large brass end where it rests on the throttle was with such engines as the 4bbl 440's which had a distributor solenoid. The throttle lever would ground the brass end, there was/ is a wire connection there, and that would activate the retard solenoid "at curb idle"
Actually you COULD repurpose this for AC. You would want to splice it into the AC clutch feed properly, upstream of the low pressure switch, which cycles the clutch off on low pressure
Frankly if you retune the engine, richen up idle, recurve the dist. and run more initial advance, etc etc, and do not have to have the car "smogged" I would simply remove the thing.
They were a PITA because most the time the solenoid did not have enough "oomph" to set the thing. You had to crack the throttle to set it. So they would almost never start and run just by turning the key
