Sprockets Engine sprocket came right off!

[WingDing]

I was riding along today and all the sudden the engine would rev but the bike would not go.

I pulled over and took a look. The chain was still attached with the sprocket hanging loose behind the cover. The nut was still there. I took the clutch cover off... And tightened it back up. It stayed tight long enough to get the engine running but then was spending freely again.

It tightened up a couple times since then... And always it stays tight long enough to start the engine and then is loose again

the key has sheared,its a very small woodruff key.
if you remove nut,slide sprocket off,you will see where key was.

I have an older motor that I've been using for spare parts. Is that something I'd be able to take off of it?

LOL it wasn't so awesome pedaling home!

Thank you!
