308 carb idle question, w/ A/C on-off...?

Guys the idle solenoid was a produst used on a lot of american cars prior to the electronics era and FI. It is a solenoid (plunger) that is mounted to a bracket and presses on the throttle lever. The way it worked is when you turned on the AC the compressor clutch engaged and at the same time the idle solenoid was engaged. This would push out the plunger maybe an 1/8 or 1/4" against the carb. throttle. Thus the idle would increase to compensate from the drag of the AC compressor. I think it would be easy to do this on our carb cars all you need to do is fab a bracket and go to any parts store to get a solenoid. Simple. Enjoy the ride

 

No hurry, Greg....its Friday!! Hope Steve's tip helps.

(Thanks, Steve!)

 

500 rpm seems to much. Something else is wrong. I still have the York piston type compressor and it only takes about 100rpm drag. The rotary Sanden compressor should be less then the york. So I would think that it would only take 50-60 rpm drag. As I mentioned before I set my idle at 1100 rpm and when the AC is turned on it drops to 1000rpm.
