Tech info wanted; Lean Burn Dist

What do you mean by WHEN? We're close, I'm 73. If you can wait till next week, I could probably do it for you. I think I have a dual pickup dist. My wife just got out of the hospital, so I have a little more time. I have to fix what I think is a vacuum leak on the engine first. I replaced the 2 bbl manifold with a 4 bbl, and it is running very lean at idle.
