Jason, there were 2 levers that Jim described. The early Cubs had the lever with the longer arm which allowed full range of the throttle quadrant. Later model Cubs had the lever with the shorter arm, which did not allow full use of the throttle quadrant, however, the results from idle to full were the same, just using a shorter range of the quadrant. I'm sure there are comparison pictures, however, I'm not sure where to look for them. Perhaps someone else can post one.
Whoops, Hengy was quicker on the draw
