So I was about to install the lighting coil I bought off ebay on this H60 I aquired a few weeks ago when I realized the coil and flywheel came off an HM80. I could have sworn I bought one from an H60. In any case are the shafts the same size anyway? Also I've heard the taper can be a little different. I would know this right away if it doesn't fit right? I just don't want to be banging it in and think it fits only to have it fly off should it start up. The current stator magnets were really rusted as well as the flywheel magnets. I sanded them clean and will do the points tonight. But I'd rather just go with installing the lighted coil and flywheel. So H60 vs HM80: close enough??
