piece missing connection off carburetor?
I was looking at my engine bay tonight and noticed this part off of the carburetor and it was not connected to anything. Looks like it should be though.. Can anyone tell me what it is? I am about to order an assembly book and shop manual so hopefully these will help me in the future.. Thank you in advance..

Question!
I agree, that is the idle stop solenoid but on my 74 is it only energized with the A/C turned on or is it energized with the key in 'run' and then used to fully close the throttle with the key off to prevent run on? PG.

I want to add it to my Carburetor Holley 4150 (HLY-0-80783C), But I can bolt in what is in the market.
Thanks

Well, that's actually an anti-dieseling device as Pete pointed out. It was originally designed to engage whenever the ignition was on and bump up the idle to the desired level. Then when the ignition was turned off it collapsed and closed the throttle blades 100% to prevent the engine from running on after the key was off. But it works Excellent as an idle boost when the A/C is turned on, that's how I have mine hooked up. Been using it several years for that.

Roger, I think some of these guys have found a new use for the ISS. I guess if you don't have a dieseling problem may as well put it to good use.
I couldn't do it. Mine used to diesel like crazy before I added the ISS.

Low comp & solid lifter cam & it didn't want to idle in gear & if you picked up the idle rpm it rev'd to high in neutral.
There was enough power in mine to pick up revs without touching the throttle
