You mentioned zero about cleaning out any passages in the carburetor….only a visual. Please elaborate.
I don’t see any drool, the motor is pretty clean.
I snaked tiny wires through the passages when I had it apart yesterday. I sprayed it with carb cleaner as well, but it was near perfect condition when I pulled it off…. The gaskets were almost brand new, there were no obstructions in any jets and the float had even been updated to the black plastic (as opposed to the original varnished cork). This was when I noticed the float was almost a millimetre off parallel. Fixing this made a definite change, but didn’t fix the problem.
It was suggested in another forum that I would need to pull the welch plug and get into the low speed circuit again? Apparently it can take a couple tries?
I also tested the fuel line, it has pretty strong flow coming out of it.
