You mean the rubber cover where you hook the vacuum gauge and that I said was really easy to drop and lose?
If you don't have the rubber cover on it you have a pretty decent manifold vacuum leak. Your car will run rough -- you absolutely, positively have to have a cap on it. A leak like that can really make a difference.

Yeah, I thought so.

Well, you can, so long as you re-adjust your idle back down to a good number after you have your mixture right. The theory being that the very best idle mixture will give you the highest vacuum because the engine is running the most efficiently. You can monkey around with it, and if it doesn't improve, monkey with it some more. You can't really hurt anything.
