The float just allows gas to fill the bowl.of the carb if your not getting enough gas into the bowl it could be the valve on the tank being clogged. But if you are getting gas pouring out of the overflow of the bowl just smack the shit out of the carb with a screw driver or a wrench if that doesn't work you can take it apart clean it and put a dab of WD 40 or penatrative oil... Other than that idk if you can or should adjust the floats.
