It also will intermittently puke gas out of the front of carb when I’m priming it.

That means the float is not shutting off the inlet gas when the carb bowl gets full.  This can be caused by the float level being set too high, float in upside-down, float hanging up on an oversized bowl gasket from a cheapie  Chinese copy of a carb kit, dirt in the float valve needle and seat, float not moving freely on its hinge, etc.

A crude test of the float and valve is to blow into the fuel inlet with the carb off the motor and empty (yes I blow with my mouth) – you should be able to blow air into it.  Then turn the carb upside down and blow into the fuel inlet – you should not be able to blow air into it, as  gravity pulled the float and shut the valve.  This checks the float valve , but if the float level is set way too high, it can still flood when priming.

Float should be level and parallel to the carb body when held upside down with the bowl off like in the photo below.  Bend the tang on the float to adjust.

OK, so you have not actually pressure tested the unit, correct?  All the new seals/orings and gaskets can not compensate for a damaged or porous casting.   You also report poor water pump output at higher RPM.  I’m remembering something that Frank Robb posted awhile back…  Sometimes these castings crack behind the water inlet cover about the AV plate.  Does oil leak out of the unit when it is just sitting in the run position while out of the water?

Like others have said, you might also just be dealing with oil exhaust drool/residue.  What does the gear lube look like when you drain it out??

…and  tell us   YES  or   NO  if the GC oil is getting contaminated with water … an oily bucket means nothing !

Are you sure your motor is running on two cylinders?   One lung down will puke a lot of oil/gas into the drink!
