Stock, they had two rings. There is a replacerment piston that uses one. Much better. Marine Specialties shoyuld be able to fix you up. They advertise in the mags.

It was a common practice to remove the bottom ring to improve the top end power on the older Zenoahs. When the factory started making one ring pistons, everyone went to that. Even now, Zenoah 260 pistons have enough metal thickness at the top to cut two ring grooves.
