383 with A/C Idle problem

[Maymarmag]

Hi Guys,

I have a 69 Newport that was originally a 383 2 barrell. The previous owner installed a 4 barrell Holley. I just had the A/C compressor rebuilt and it is blowing cold, which is great. Problem is when the A/C goes on the idle goes really low to the point of cutting the engine off. Works fine if I put it in neutal and give it gas, however. I have been told that there should be something (solenoid, etc.) on the carb to kick the idle up on the carbeurator when the air is on. Can anyone shed some light on this and/or what I need to do to remedy this?

Thanks,

Pete

Here's a NOS one. Aftermarket ones are cheaper. Late 70's junkyard ones are the cheapest.

Wire it to the wire that goes to the compressor. If the compressor kicks in while the throttle is closed (as in idling) a plunger pushes out and moves the throttle linkage a hair to increase the idle.
