This may cure problem, only time will tell since the problem is infrequent. Maybe the clutch is wearing down due to the new control system which may be driving the mechanism for too long after it stops, causing the clutch to slip a lot. I think we should cut back on the drive time to what is barely needed plus maybe two seconds, to extend the life of the clutch. PICS COMMENT: Sun Jan 11 21:27:51 GMT 1998 Stalled with Program: K-corona, not sure how long since I was up in the dome for a while working on MK3, fixed with Kill/Run.
