So I fit a working Vespa clutch to this engine and when it finally kicked over and put it into gear, there was massive judders as I let the clutch out. Enough to cause me concern
Today I have removed the clutch to see if there was a spacer washer between the clutch housing and the crank, thinking this may be the reason. But it does look like it is in place, see photos. However, it is jammed on the crank, in that it does not spin round, could this be the reason for the judder. I appreciate that the problem may be the cush drive, but I want to eliminate one thing at a time.

Plus, can I replace that stupid castlated nut with a more modern Cosa nut????
Thanks
