Title: Throttle lever assembly

Abstract: A throttle lever assembly for controlling the actuation of a throttle valve in an internal combustion engine has a throttle shaft pivotally secured to a housing. An idle stop lever is mounted to and radially extends from an end portion of the shaft for engaging a depending member of the housing to stop the rotation of the throttle lever assembly at an idle position. A return cam formed of thermoplastic/thermoset material is overmolded the end portion of the shaft and a portion of the idle stop lever. The molded return cam has a channel disposed about its cam surface for receiving an accelerator cable, a stud extending axially from the outer surface of the cam return, and a spring retainer extending axially from the inner surface of the return cam for maintaining a return spring in coaxial relationship with the shaft. The return cam may also include an idle stop member to replace the discrete idle stop lever. This fully integrated return cam is secured to the shaft by overmolding the return cam to the shaft which has grooves disposed transversely there across which function to prevent axial and rotational translation of the return cam relative to the shaft.
