Those carburetor float adjustment tools will drive you up a wall. Now, as that very trustworthy carny at the circus said one time.... "Trust Me!"
(Carburetor Float Setting)
(J. Reeves)
With the carburetor body held upside down, the float being viewed from the side, adjust the float so that the free end of the float (the end opposite the hinge pin) is ever so slightly higher (just ever so slightly off level) than the other end. And when viewed from the end, make sure it is not cocked.
