how long have you owned it? how much run time have you put on it? thanksI got the saw from a home owner it's never bn a loggers saw, it was a barely used firewood saw. There piston is still got some shine to the top of it so it has no time on it. It's completely original it's never had a sprocket put on it. I put a new plug and airfilter on it. If it don't sell I'm gonna port it next week and then the price will go up.
