Manco 495B-09 problems need help

[Metricmike76]

I cannot get the chain to stop slipping off the sprockets, I recently put on a new jack shaft and replaced the bearings and tabs in the clutch by the green spring. Anybody near Genesse county Michigan?

Are the sprockets in good condition? Check alignment too. Not only must they be in perfect line with each other, they also must be dead parallel. Use a good straightedge to check this. Check shafts for warpage/bends, too.
