OK guys, I need help. While I was flying my Giant Stinger my engine fell off. That's right, it fell off. Luckily my airframe is fine. My engine is not. That's where you come in.

I have a Byron Mustand 50. At least that is what I've been told.
It has a bent crankshaft. It's not bad, but just enough that when you turn it over, you notice it. It is/was a fine running engine.
Please help tell me what to do with it. Who to send it to, throw it away, or let a small engine shop turn it out.
I bought this over the net and didn't look at the firewall area good enough.
Thanks for any input and please help.
