Okay, so it was idleing (idling?) too high because I was stupid. So got that fixed now, but it still idles higher than I like. I'm pretty sure it has something to do with vacuum at this point. When I hit the throttle the secondary valves in the air horn don't open (held shut by vacuum), but it delivers a lot of fuel and makes a bunch of smoke (running rich flavor). So are there some vacuum connections that I'm missing? It's a Quadrajet carb with a thermostatic choke. I see one vacuum hose (I think) coming from the distributor area, but didn't really investigate to find out what it was hooked to. I think this hose connects to an outlet on the side of the carb, but does anyone have any insights?

On another note, I broke a stud for the thermostat, but there's still a little piece of the stud sticking out, so if I shoot enough penetrating oil in it should it come loose at some point? Of are there other ways of extracting it?

Sorry for so many questions and longwindedness, just trying to sort out some things...Thanks in advance.
