Yes, it WAS a sheared flywheel key. Thanks Folks. Went to my diecast bucket and found a used one which in put in with the help of a neighbor. Will start and run now just don't have the linkage hooked up right so isn't running as should. Can any one post a pic. In meantime i'll see what I can find on YouTube.
Was not able to find something that specific on YouTube.
Seem to have throttle and governor linkage hooked up properly now and all parts back on. Torqued flywheel nut to 40 ft lb. Does this sound right? It had loosened up after first successful start up. Tomorrow gas in tank and cut-grass test.
