Quadrajet and A/C question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a K25 GMC 350 mouse motor with a qjet and A/C. When I turn on my A/C it drops the idle just a little, when I'm in park its no big deal, but when it is in gear it wants to die. I have been going through a lot of my old manuals and cant find what I'm looking for......So I think there is supposed to be a electromagnetic solenoid mounted to the carb that is activated when the A/C is turned on and bumps up the idle. Can anybody help me out, am I correct in my assumption? and does anybody have one?
