The problem is that the throttle pedal is "bottoming out" too soon. The
throttle linkage running from the lever on the throttle pedal shaft to the
bell crank (under the carbs) is adjustable in length. If you shorten this
linkage you can gain more throttle pedal movement and recover the throttle
plate movement you desire. This can compensate for sloppiness in the
linkage joints and pivots and is a "quick and dirty fix" not to be
confused with "fixing it right" but it will keep you on the road and
grinning!
