I recently inherited a McCulloch Partner chain saw of unknown origin that his been sitting in an attic for at least 15 years. It has a 30" bar and looks as if it was outfitted for professional use. Does anyone know how old this saw is, specs (displacement, maximum bar size, etc.) and if I can "safely" put a shorter bar/chain on it for use. It started on the first pull after I cleaned it, replaced the fuel line and spark plug and a few other minor mods.
Thank you.
