I think He( WE) needs to know which holes to use to put the clutch shoes on the flywheel. I was wondering the same thing. I mounted them on the leading part of the shoe. meaning pull the pull start and see which way the flywheel spins, then install the shoes so when the flywheel is spinning the pinned side of the shoe is leading the way and the back can just fly out behind and contact the clutch bell. This maybe wrong but HOPEFULLY someone knows for sure and will post! As soon as my parts arrive I will find out for sure! LOL
