I saw an ad for a Stihl 020 AV on Craigslist for 5$. Called the guy right away and he said I could have it. I don't know the first thing about these saws and I have no need for a top handle saw, but for 5$ how can you go wrong? It has good compression and it starts but won't stay running. He said he thought maybe it was the pickup and he had replaced that but that didn't solve the problem, then he said he thinks it might be a problem w/ the carb (diaphram). I'm gonna see if I can get it running.
