This has not effected the use of the saw in the past (the crack is visible in the photos, especially the last two photos). Please refer to the photos for more details. This saw has good compression; good spark; the recoil starter assembly works as it should; the compression release works as it should; the chain oiler works as it should; the safety chain brake engages and releases as it should; the clutch works as it should. However, the chainsaw will not stay running - upon starting, the engine accelerates quickly then dies off and quits as if starved for fuel. Perhaps caused by an air leak in the fuel supply, or the carburetor needs to be rebuilt or replaced, I'm not certain about the cure.An ebayer asked a question about a failed piston as the cause. My answer is this: I removed the muffler and the spark plug. I looked through the exhaust port with a flashlight and worked the piston through a few strokes and saw no evidence of scoring, just a nice bright shiny piston smoothly working away. As with any 60cc Stihl, this saw must be held to the ground with a foot or knee prior to pulling the starter rope, the compression is just too great to try the old macho shoulder drop start like you can on a lesser saw. The 036 Pro has a compression release which de-activates instantly when the motor fires (as it should).
