Idles rough when AC turned on - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My 1985 K20 with the 350M 8600GVW HD Emissions package idles rough when the AC is on. I see on my Air Cleaner sticker that the idle speed solenoid is supposed to be set to 800 RPM. I don't think I see this on my carb.

Here is my carb number: 17080230

Here are some pictures of the carb. I don't know what I am looking for and if I am missing it can it be added to this carb? And how?
