Abstract
An improved throttle control which includes a metal throttle lever, a metal bracket, a plastic detent plate and the lever being pivotally mounted to the bracket with the detent plate therebetween and a spring biasing the lever toward the detent plate. The detent plate includes an annular ridge facing the lever and immediately surrounding the mounting means and an arcuate ridge facing the lever and spaced radially outward from said annular ridge. The arcuate ridge includes at least one recess which coacts with a detent on the lever to provide an easily detected preset throttle position. The detent on the lever rides on the arcuate ridge and the force necessary for lever movement is determined by the friction force created between the lever detent and the detent plate arcuate ridge. The lever also includes an arm which engages a throttle cable and the bracket receives and secures the end of the throttle cable sheath.
