Well I’m stumped. I had at it again tonight. Tried adjusting the drop limit, swapping floats, swapping needles, all without improvement. If I leave the bowl off and apply light pressure on the float, it cuts the fuel flow well, even against the primer bulb pressure.
Frank, where does the bowl vent to? I am not sure that I fully understand what you mean about the bowl vent. It seems to me that the fuel is getting forced into the high speed Venturi through the high speed needle seat/valve. If I seat the HS needle, then the bowl will build pressure and force the float up hard, stopping the fuel flow.
Imp have done 20+ of these carbs, and none have given me this much trouble.
