flywheel again!

can anyone tell me if a 6 volt flywheel is the same on a 50 cc engine as it is on a 70 cc one???

There are appr. 10 different flywheels / stators for 6v crank.

First, you need to have a complete set of the same brand.
For example, the Hitachi and Mitsibushi condensators aren't interchangeable.

Second,the flat Hitachi can only be replaced with a flat Hitachi (no retarding / advancing Mechanism) (Short crank tap)
(used on some ST50, z50a, cf50, ST70)



All others are for use with a long chrankshaft tap. Hitachi, Nippon Denso, Mitsibushi,...
(used on al models). Can be retarding, unrestricted or advancing.

Waynus, thanks for your reply, I have just got a complete engine off eBay 1970 st 50, looks to be right, fingers crossed.
