Abstract
A throttle valve shaft projecting from a boss on an internal combustion engine throttle body has a nut which is adjustable for establishing a selected clearance between the nut and the boss to thereby limit end float or axial displacement of the shaft. A lever or other retainer secured to the shaft has an interfering engagement with the nut to prevent rotation of the nut about the shaft and thereby maintain the selected clearance between the nut and the boss.
