RE: Echo SRM 231
It was done as a wacker. It sat in the weather. There was water in the case and jug. The carb was shot. The forged part of the crank was rusty. The bearings even felt bad. After a carefull clean up the only real damage was a bit of pitting on the cylinder bore under one of the transfer ports.
It is quite a runner, over 9K with a 15x6 using that little carb and no muffler. I think with some tinkering it will really sing.
