Unfortunately my girlfriend's father has had some health issues and has been confined to his house for several years now. The other day I found a Stihl 065 in their barn, which he said hadn't been cranked in about three years. I use a Stihl 390 for firewood cutting and general farm use (I really just like to run saws and cut wood I'm not proffesional by any means) but anyway I too his saw out put some of my gas and bar lube in it and it cranked up almost immediately. I don't know how good the saw runs though and am interested in tuning it up what would you recomend I do?
