I was given what appears to be a 1976, 1.9 cu. in./12" craftsman chainsaw, that seems to have good compression, nice bar & chain etc., problem is, the oil and the fuel lines became brittle and have crumbled, hence it being a give away. Ironically, the fuel line can be snaked through the passages, but the oil line will require splitting it in half which I hate to do as I'm not sure if gaskets are available or if I'll need any new parts. I did find a set of schematics on the sears parts website, but they are not so clear, and I think parts for one of these are all discontinued, unless anyone knows different, from another source. The real question is, after looking in McMaster-Carr's catalog online, what tubing material type would be the best choice to use for mixed fuel,and chain oil ? I'm not sure what the temperature would be in the engine compartment, but I'd think something that handled 400 deg F would be required, anyone have any suggestions, I know nothing about the materials listed. I think 1" bending radius will fit without kinking. I thought it would be neat to get it going and use it for limbing and or light work, my Stihl MS-390 takes care of large jobs. Appreciate any insight, 1st old chainsaw project, Dad's late 1960's Stihl 085 is next, sprocket, chain and bar seems to be all it needs, it runs good. Kinda heavy, but a classic now !
