I just put the new belt and idler on, this time I put the idler on right. Got everything torqued to spec and put fan belt back on. Everything went back on nicely. Stood back and cranked her on. Boy does she sound pretty. No smoke out of the stack, cranks right up, and let her run for about 30 min on high idle. retightened the fan belt put all the metal back on and burned some 5/32's for a while. all seems well. I guess this shade tree mechanic got lucky this time. Now I'll try to put on another 3000 hrs.
