Hello everyone. I just recently scored a lot of 18 chainsaws from facebook marketplace and am looking for manuals and information. One of the saws that I was able to get running is a Craftsman 3.7/18" Chainsaw. The model number is 917.353760 and the serial number is 2418M20866. From what I can determine online this is a Roper/Craftsman saw as opposed to a Poulan/Craftsman saw. Does anyone know where I can find an owner's manual for this saw? I have no idea how old it is or what the value of it is either. It has the power sharp grinding stone built in, in addition to some other buttons I'm not sure on. One thing I was able to find online is the fuel oil ratio for this saw is 16:1, which I have never seen before!
