a friend of me wants to restore the engine of his 4010, but he can't find the engine number. In the JDPC he has found the declaration "early design" and "late design" for the crankshaft.
It would be nice, if some will explain me the differences and the production periods of the late and early design. Thanx
edit: I think, this is the wrong forum (I've only looked for 4010, not for the series) - maybe one of the mods can move this thread to right section, thanx again
