I know you replaced the nozzle gasket but your problem is the classic symptom of a missing/worn nozzle gasket. I guess you will know more when you swap carb bowls, unless the carb nozzle casting is flawed/cracked/porous.
I don’t think there is anything in the intake manifold that would cause it to run rich, so I would rip into that. The only other thing that comes to mind is a plugged exhaust/intake, but you have already been there and would have seen nests, mud dobbers, etc.
