Proper fuel level is at the "pip" near the center of the bowl cap. Place a 12 to 16 inch length of 1/8 " ID clear tubing over the idle jet, curve tubing into a manometer to see fuel level when the cap is in place. Add (increase fuel level) or remove (decrease fuel level) washers under the needle seat to adjust level.
I agree with Beach .... The float is correct, but the needle and/or seat may be incorrect.
