Help needed with sb 318

Good news.....bad news.

Good news is I swapped out the condenser.......and she started up and ran.....meaning I didn't do any harm.

Bad news is.....made no difference. Still stalls if you rev the engine. I also swapped out the vacuum hose that runs from the carb to the distributor.......and that made no difference either.

Timing? She does not backfire. She runs ok, so to me, plugs, points, etc. may help, but are not the issue.

Circling back to the carb. History of that.....first thing I did was to pull the old Carter BBD carb....no number on it, but found a kit. Handed carb and kit to a guy who I'm told has done a couple thousand carb kits. Full time job is rebuilding engines.......hobby is building engines for drag strip cars and pulling tractors. I would hope if he did the carb it was done right.
