I did a little research on Caber and it looks like they have a very wide assortment of piston rings for about anything .
In a way relatively speaking this two cycle stuff is rather new to me .However nearly all my adult life I've tinkered with old stuff like tractor engines .I have never had a problem finding piston rings for them .Most of them for those of the Woverine state are made in Muskegon Mich which seems to be the piston ring capitol of the world or was at one time .
