I have a 051 that I would like to sell. It is not real pretty as you will see in the pics. The rear handle has been welded. The recoil has a junk broke out and the front mount needs welded. It starts and runs and that is about all I know. When I got I put new gaskets in the carb stack and replaced the screws. I not much more with it. I comes with about a 26" bar and chain. I believe it should be worth $135 plus shipping.
