Cub Jumping When Clutch Released

[B. White]

I was looking at a video of a Cub someone is selling and it had a little bit of a lurch starting off in forward. He stopped and went in reverse and it was more noticeable with him bouncing in the seat four or five times before it smoothed out. It is hard to tell watching it, but I think it is the operator looking at the way he kept his feet on the clutch and brakes. Curious if there is a common clutch problem that would cause one to jump this way.

Most common problem I'm aware of is an old clutch disc with smooth surfaces and greasy buildup on them. Makes for a nearly impossible feathering action when starting off in either direction.
