So, I picked up a Stihl 036 Pro recently, supposedly real low hours, and the engine definitely looks it. Not only is the piston not scored, it doesn't even look like it's broken in! Pulled 155 PSI on the compression tester after a 60 second warm up, with a barometer of 29.72 in, so 10.6:1 compression. I'm happy with the motor. However, it looks like the guy who owned it did not believe in bar oil. The bar is totally wasted, blue down both edges and badly worn. Four chains (two green, two yellow), all with some wear on drive links and tie straps, and the rim sprocket is also showing some wear where the rivets ride. It actually doesn't add up, to have such a clean motor with such a trashed bar, the story being this was the guy's only saw, and he didn't use it much. Oh well... Who can recommend a good new bar for an 036 Pro? I've always run sprocket nose, and don't mind keeping the sprocket greased, unless someone wants to convince me I should be running something else. I've also been running 33RSC or 33RSC3 on my other saw, but again, could be convinced otherwise.
