This is an authentic OEM sourced replacement piston ring which is used with Poulan chainsaws. A worn or broken piston ring will allow combustion gases to escape the seal and enter the crankcase, causing low compression and a loss of power. If compression is reduced significantly, the engine will not run at all. This part is made of high-quality metal and it is sold individually.

Lesson learned was that it can be more than a fuel or ignition spark issue as a reason the engine would not start.
