Well...my original center crankcase has a structural crack in a semi-circle pattern. Cleaned up left and center crankcase halves. Had to use the one from the scooter engine. New crankshaft fits like a glove. There is very little front to back movement. Just enough for proper clearance. Starter clutch is still giving me a problem. It locks up as soon as I tighten the flywheel nut. Not sure what I'm going to do but I'm certainly not going to finish the built till I get this sorted out. The starter gear, clutch and flywheel are brand new. Really can't put my finger on what is happening. There are no more clearance issues with the timing chain and oil pump chain. Going to try again tomorrow to see if I can figure it out.
