ABSTRACT:
A throttle control for connection to an engine throttle control wire broadly includes a shifter and a case, with the shifter including a rim which engages a corresponding bearing wall within the case to define a circular shift path and which enables the throttle control to be converted for either a positive-action or negative-action mode. The case includes a first portion and a second portion, with at least one of the portions preferably including an inner wall spaced radially inwardly toward a pivot axis of the shifter and away from the bearing wall. The inner wall preferably includes one or more recesses thereon for engagement with a follower on the shifter whereby the shifter may be releasably held by the recess at a preselected position along the shift path.
