I MACHINED A HUB FOR A CONVERSION IM WORKING ON BUT IM NOT REAL HAPPY WITH THE OPTIONS. I DONT LIKE THE FACT THAT THE FLYWHEEL SURFACE THAT IT SITS AGAINST IS NOT MACHINED. I HAVE A .750 DIA FLANGE AGAINST THE FLYWHEEL BUT IM NOT SURE IT WILL RUN TRU ENOUGH. I TAPPED THE 8MM SIDE .437 DEEP AND THE PROP SIDE IS TAPPED 3/8-16 ALL THE WAY THROUGH TO THE 8MM THREAD SO I CAN PUT A SETSCREW INSIDE THE HUB AFTER ITS TIGHTEN AGAINST THE FLYWHEEL TO LOCK IT ON. I MACHINED A 1.250 DIA. FLANGE WITH A .500 DIA BOSS ON THE PROP SIDE AND COUNTER BORED THE PROP TO SIT OVER IT TO INSURE PERPECT CENTERING ON THE HUB. IS THERE A PROBLEM WITH HUBS COMING LOOSE FROM ELECTRIC STARTERS? HOW DO ALL YOU EXPERTS DEAL WITH ALL MY WORRIES?
DIFFERENT SUBJECT- DO I NEED THE FLYWHEEL IF I USE A PROSPARK CDI IGNITION SYSTEM?
