Just Thinking about the lock up. a poster earlier reported that visually it looked like the driver on the left side was pushing outward. So thinking ,those who reported the lockup and then jiggled the center driver, i was just wondering if you may have noticed the center driver pushed against the drive rods and maybe stuck there before you jiggled it free.
I have a central Vermont engine. I notice the hesitation, lurch or jerk in slow speed up to speed step 30 or so, more so accelerating than decelerating. Seemed to be able to mitigate the non smooth motion a bit by modulating the throttle in the speed step range where it occurs. Also the hesitation was barely noticeable on the rolls step.
I have run this engine for about an hour or so , in the slow speed step which is above speed step 30 , smoke off and although hesitation was noticeable as described (under speed step 30) when accelerating from stop to slow, I did not encounter any lock up condition . Smoke was not on most of the time.
Sharing my experience and awaiting word from Lionel.
