Vernier-Assist Throttle Control Assembly 
How to reassemble the roll pins in a McFarlane Vernier-Assist throttle control.

 

 

This control has all the fine adjustment benefits of an old style push-button release vernier control, with the simplicity, responsiveness, and jam-proof safety of a friction lock control.

 

These light weight controls use a patented drive mechanism. The new roller action vernier provides smooth, jam-proof coarse and fine adjustment without a release button. Coarse adjustments are made by pushing the knob inwards or pulling the knob outwards. Fine adjustments are made by rotating the knob clockwise or counterclockwise.
