If you cant get it to idle down more than 2000 I'd say you have a massive vacuum leak somewhere or the throttle blades are sticking in the bore.
double check all your vacuum lines, I.E brake power booster vacuum line which is a big one that will cause that problem. PCV vacuum hose is another. also spray some carb clean around the base of the carb and see if rpms pick up you might have a base gasket leaking.
Also I'm not real sure about an edlebrock carb but Holley's have a secoundary throttle bore idle adjustment screw that kinda hard to see. might look around the secoundaries and see if there is one on your carb it might be tweaked alittle.
Goodluck. Charles
