Abstract

A drive lever mounted adjacent a throttle shaft is connected through a link to a throttle lever secured to the throttle shaft. The link is contorted to initially engage the throttle lever at a location which provides a large lever arm for initial throttle opening movement and to thereafter engage the throttle lever at a location which provides a smaller lever arm for subsequent throttle opening movement. The link further engages the throttle lever in a manner which assures throttle closing movement of the throttle lever over the entire range of throttle closing movement of the drive lever.
