You can check the float level without disassembling the bowl by
screwing a jury rigged fitting into the 1/8" pipe plug bowl drain port.
Connect a short length of small clear flex hose to the fitting, hold
it up, & see where the fuel levels out to. I don't think you will find
it wrong though.

The comment on the accelerator pump maybe being goofy is interesting.

The float bowl vent is to the air intake side of the carburetor, but I
don't yet see how that could cause your symptoms.

Hmmmm......
