Do you by chance remember changing the "power valve"???
I have seen these work loose (and go bad). Since they are located below the fuel level in the bowl, if they are loose and or "leaking by". The engine will run rich, and as you said, get progressively worse.

Some kits have one some don't,
this could still be the problem if it is leaking
or "passing gas" when it shouldn't

Did you replace the float valve seat and needle? There is also a filter screen in front of the float valve, be sure it's clean. Blast out any little hole/passage you can find. :cool: Wear glasses!
What about the fuel filter(s)?

If you lose power in a hard right you need to raise the float level.

a massive vacuum leak or plugged idle circuit, sounds like your other carb is in better shape, reset float levell and check vacuum routing. Check that the bowl vent valve ( black round valve that clips into back of air cleaner) is connected to the very top port of carb, above fuel line fittings & not the secondary air control port on the back side. If fuel is spitting from the primary venturi at idle, you have a plugged idle circuit, and it's sucking fuel from the main circuit.
