Can't make a bushing,no lathe, still would need to cut crank and true up to some uniform size to make bushing fit ? Would need to pull crank to have new keyway cut,work either way I suppose, I have a spare engine and likely will make one good one out of the two ! This one runs good, no smoke but has an internal problem with the gov so I need to open it up to fix that issue, reset gov a couple times to be sure,must be a broken gov or weight off or something , no resistance on the gov arm when running ,looked at everything external I could think off so I'll get the spare up and running ( not sure of it's condition ) or fix this one !
