This is a genuine replacement part manufactured for use with outdoor power equipment. The piston ring creates a seal between the piston and cylinder, and separates the combustion chamber from the crankcase. A worn or damaged piston ring can allow gases to escape which can reduce compression, and cause the engine not to run. Damage to the piston ring can cause damage to the cylinder, so it is recommended to inspect the cylinder for damage when replacing the ring. The ring is sold individually, please see model diagram for additional parts.

Also had to pry off high rev limiter cover and readjust the setting. Runs like new now.

Disassembled the engine and found that the ring was frozen. When I tried to get it off, it broke. I ordered a new ring and replaced it. Put the engine back together. For me, it was easy, but for others, it might be hard.
