Too much fuel?

If your timing is even close, the firing order is correct and you have spark at the spark plugs, it almost has to be too much fuel. Can you look down the carb and see fuel dribbling? I see you have a new fuel pump? It may have too much pressure. 5# is fine, 10# will cause what you are experiencing. My friends Super Bee went through 2 mechanical pumps before we put a fuel pressure regulator on it. That fixed the rich running problem. Something to look at.
