Pat:
Yes, you are correct, although there is a different way to skin that cat...probably will save that for another post.
On aluminum flywheels.......
I would love to see McLeod go to either a helicoil insert, or even better, a threaded steel insert on their aluminum units. I have seen flywheel to PP mounting holes stripped even when using properly prepared hardware properly sequenced and gradually torqued to spec. Slight weight penalty, but certainly worth it, particularly in disassembly/assembly situations. Probably a cost consideration...no?
