4 Where can I purchase piston rings by size.
I am looking for (2) piston rings that measure 1 7/16 expanded diameter (for 1 3/8 bore) by .045 axial thickness by .06 radial thickness. That's about 36.5 x 1.2 x 1.5 mm.
they fit a Yardman ym71ss string trimmer engine. I've tried ebay , Jacks, and amazon and they either sell by part number or only handle certain sizes. Thank you.
