I found a stihl 031 with a 16'' bar on craigs list today. I went to look at it and was amazed in the condition. the old owner said he bought it new in the 70.s. It started right up and sounds like a race saw. He said that he has never done any mods on it. I guess back then the epa didnt have their hands in them. Any way im pumped I paid him his asking price of 80.00 and think I gotta nice old saw to play with. What do you think?:greenchainsaw:
