Look at Don's post. for the 80321 carb the float setting is parallel to fuel bowl when bowl is inverted. You will have to pull off the fuel bowl to adjust it. Is yours externally adjustable? aka does it have a nut around a screw on the top of the bowl near the side where the fuel line comes in? According to the part number you gave me, it is externally adjustable. If so, invert the bowl and see if the float needs raised or lowered to be parallel with the bowl floor. Adjust it using the directions in the picture.
