The lines were never disconnected. I have no ether available to try just now -- but the engine doesn't hit at all.
One item I faileed to mention earlier: I first cleaned the muffler guessing it might be the problem, and when I reassembled the 'eater it did start right up, only to run only at idle. Thinking I'd not cleaned the muffler well enough, I again cleaned it using gas as before -- and when I reassembled it again, it would not "hit" at all. It's since then that I've sprayed muffler, air filter and carburator with carburator cleaner
