No start after intake and carb swap. Stumped

Pass side float sticking [ closed ]? Acc pump gets it's fuel from drivers side fuel bowl, so pump shot only tells you that that side has fuel. Rap the carb top with a small hammer where the n/seats are to loosen them.

Also look for fuel dribbling from pri boosters. Could be flooding, o ring problem [ missing ]. Etc
If still no go, remove carb top to check for binding/float rubbing. Congrats on the TQ, good move!
