All parts are good just put in new starter, but that was not the problem, so I pulled of the magneto thinking it was the starter clutch, but now the crank shaft turns smooth 1/4 turn in ether direction then locks. I'm going to check out the clutch basket which I updated to barnet plates and $250...
Where one of those ends of that assembly goes into the thermostat housing is there an O-Ring? I cant believe that will seal with just a bubble flare pushed into an aluminum housing. Nice pics btw.
My 1985 runs an 1/8" below the red line when it's very hot in traffic, but years ago I checked it with a thermometer and that's 195% I think, so I don't worry unless it's almost buried.
