Hi
Darryl,Thanks for posting that pic, I have noticed something I have not noticed before on the early solid deck Series 1 Scotties and that is an engine clutch thrust washer (Illustration No. 135 and Part No. 331803 in the SB 45 Parts Lists) placed between the brass thrust pad and the clutch cone.
It was obviously deleted when the plastic thrust pad was introduced on the Series 2 machines.
