That’s a 1941 decal – parts are still around – The Elto Ace and Evinrude Sportsman used the same pistons. The Lightfour uses the same piston rings. Part number 101267 it says on my piston ring box – A gentleman at our international meet had 50 boxes. Since I have four Lightfours …
Lightfour pistons will not work because the wrist pin hole is 90 degrees out of phase. . . . 😀
