I have a very old Stihl 08S chainsaw that needs the bar, chain, and fuel cap replaced. It has a I.D. plate on the top of the oil tank # 4816750, which I believe is the serial number. The original 17" solid bar is still installed, and it has 60 link 0.404 pitch chain. It was working until recently, and I would like to restore it. I have no idea how old this chainsaw is other than I inherited it from my step father years ago, and I personally used it when I was a teenager. Any help would be greatly appreciated.
