Lightly used chainsaw, roughly 15-20 years old. Only used 2-3 times per year for cutting up branches. Starts but currently DOES NOT RUN. After starting, if you hit the throttle, the motor dies. It most likely is due to very old gas in the tank that has gummed up the carburetor (but no guarantees that that is all it is). It came with 2 chains and the second chain was put on it just a few years ago, so it hould be fairly sharp.
