One more thing to check are the throttle cables.  When you twist the throttle, does it snap back pretty quickly?  They should.  If not, you may have a binding cable or a bad return spring on the carb bank. If it's not a mechanical problem, then I'd go chasing the vacuum leak.

After you find the source of the problem (vacuum leak wise), getting your carburetors sync'd up will probably help as well.  Search for "carb sync" at the home page of our happy little forum, and you'll find LOTS of discussion about it.  The tools will cost you about $75-100 US. Or, if you wish, you can take it to a repair shop, and have them sync them for you.  Everything, and I mean EVERYTHING else needs to be working well before doing the carb sync (valves adjusted, no vacuum leaks, compression good, etc). If not, you'll just need to do it again after you fix the other stuff.

I remember getting my carbs in sync, and I had to turn the throttle stop down quite a ways to get it to spec.  It ran SO much better afterwards.
