Perhaps a compression test is one of the first things that should be done. Remember to do this with the throttle wide open.
If you remove the carb for rebuilding why not go ahead and install a manifold gasket set. Easily done and can really make a differce in idling if there are leaks.
My opinion, if the compression is good rebuild the carb, put in gaskets, then use a vacuum gauge to seek some more on what is going on. A vacuum test can reveal valve problems, etc.
Word hard, play harder, enjoy life!
