I'm going to be trying to sell a chainsaw for my mom. It's a Stihl 029 super. I know nothing about them... at all.
My dad used it one time and then stored it for the last 4+ years and forgot to empty the gas. Before I try to sell it I need to know that it works. Should I empty the gas and add new mixture to it and try to start it? Or should I bring it to "kitz and pfeil" and have them do a tune up on it, even tho it would probably me cost anywhere from $40-$100?
Are there any parts other than the fuel line that could have been damaged from being stored with gas in it?
