Take a look underneath and see if the bottom of your engine is wet with
oil, especially toward the rear in the direction of the tranny. If so,
you may have a leaking rear shaft seal.

My machine has that problem and it has definitely got the "jitters" or
clutch chatter. The seeping oil is not enought to even drip on the
ground, but it's enough for the centrifugal force of the rotating parts
to distribute on the clutch face and fly wheel. Enough to cause chatter
on starting off. I've put off the repair required, and to avoid the
chatter I have to let the clutch pedal out quite forcefully for a solid
engagement to avoid the chatter.
