I am the new owner of a used (free!) stihl 029 chainsaw that the previous owner ran straight gas through scoring the piston and cylinder on the exhaust side. I have it all broken down a convinced that it is worth saving. My question, I don't want to spend the small fortune that the dealer wants for a piston and jug (I almost fell out of my chair, be better off buying a new one for another 100 bucks) how decent are the ones on ebay for right around 100 bucks that they call no name aftermarket. There are a ton of them, just wondering if anyone on here has tried them. Thanks for any insight.
