Reply To: Mercury KE4 Piston Ring

Okay now that makes sense. It’s probably the reason I keep breaking rings. Luckily my ring pins are still fully intact. Once I get my new rings I will make sure they are all aligned with the pins and use a 2 stroke plastic pin compressor.

My cylinder walls are in great shape but the pistons have some carbon scoring I can’t get off. Any suggestions?
