I don't know much about the saw but seems to be a newer model of a pro mac 700 right before they ended production altogether. Asking $800.00 shipped O.B.O. I can throw the bar and chain in for free if you pay shipping costs. The saw runs and idles fine, the auto oiler does not appear to be working but manual oiler works. Coil was bad when I bought it so I replaced with an older coil off of a pro mac 700. I also replaced fuel line and rebuilt carb. Fuel cap and fuel tank gasket need to be replaced. Can send videos of saw running upon request.
