Bucking and stumbling while crusing at constant speed and light throttle
pressure (light load, level ground).  Most pronounced at 35-55 mph, but
that was all I drove it at before I fixed it.  You won't have problems
under acceleration or heavy throttle pressure because the switch opens
then, but not at light throttle cruising when it is misadjusted.
