Purchased a 1972 green CT70H 4 speed manual clutch. Does anyone know the differences between flywheels, 4 speed manual vs. 3 speed automatic? My take is that the 4 speed had a timing advance mechanism inside the flywheel as the 3 speed did not? Any help would be appreciated.
I believe so. The 4 speed flywheel has a timing advance mechanisim on the inside of the flywheel as the 3 speeds do not. Can anyone out there elaborate on this?
