Set the float to spec.but check the needle and seat by ,when you got it apart , hold the top upside down with float installed and try and blow air into the inlet to see if the float needle is seating right if thats good it could be to much fuel pressure ,not common ,but it does happen. Cheating on the float will make you're carb not work right there are passages in the float bowl that need to have gas in them for the carb to operate .Also you need to make sure that you're getting fuel ,check for a cloged fuel filter.It's important to set the float to spec both ways up and at the bottom.
Is the carb a mod. B ?
