Thanks for the input and suggestions. I don't think I have the chain anymore, but will post a pic of the bar. As to investing in a new bar, I have another burnt 026 I picked up at auction without a bar, so I will use this bar if it checks out.
I moved into the city a few years ago and dont really have a use for my saws anymore, which is kind of sad since I used to enjoy fixing and using them on 50 acres. The 026 is going to a friend who was contemplating buying a throw away saw for some clearing work. Since I have another 026 and an 009l in good shape, and this one has just been sitting, almost but not quite completed, I decided to ressurect my hobby. There is still an 011 and an 012 to complete, and then there is the third burnt-out 026 and an 034 from the auction referenced above to take apart.
I was reminded that this saw-collecting thing is kind of a drug when I couldn't say no to yet another "new" saw, a neglected 025 that cosmetically looks rough but seems to run just fine. The plastic is discolored, and both the starter and handle have small cracks but are completely serviceable. The poor saw does not appear to ever have been cleaned, judging from the build up on the motor and case. I need to get access to an air compressor to blow all the dirt away, and I suspect i will succumb to replacing the cracked plastics for no good reason other than I can.
