One (additional) possibility would be the secondaries. There is a secondary stop screw that prevents them from closing too far, and you may want to make sure it is set correctly.
I never did fix my old Holley, but I looked at it and the secondary stop screw was set wrong. Which is probably why sometimes it ran fine and othertimes it had trouble idling.
But then again, if it was rebuilt it should have been checked and set.

I just discovered something that I don't think is normal:
I replaced my throttle cable a few days ago and was under the hood checking to make sure I was getting full travel at the carburetor. The engine was cold and hadn't been driven in a few days. After opening the throttle all the way a couple of times, I noticed fuel was seeping at the spring for the throttle linkage. I dried it up and opened the throttle again, and fuel ended up on the throttle spring again. I tried to move the throttle shaft to see if it was loose, but it is tight. I checked around the entire carburetor and noticed that the power valve gasket looked shiny, like it was wet.
What would cause fuel to seep out at the spring for the throttle linkage? Is this what is causing the erratic idle I am experiencing?

I was curious if you installed a return spring to help keep the throttle all the way forward when not accelerated? I did not have one at first and installed a heavy one, solved my similar issue a few months ago. I hope this may help you...
