Here's my next project saw. I got it from Rob, Stihl 041S, at the GTG. It's moel # 917.60029, has 77cc, and was introduced in 1965. LINK He picked it up at auction for................$12 It turns over and seems to have good compression, but I'm not getting any spark. It could be anything at this point. The spark plug itself is ancient. I'm undecided as to whether I want to just clean it up or paint it. Which would be more appropriate for an old saw like this?
