These old Jahas pistons I have came in this old 312.These rings have what appears to be a bevel top and bottom on upper ring.They also appear to have several lines around curcumferance.The engine only had 2000 or less miles on it and I planned on reusing these unless there is a better option.
How does this style ring work?I do not understand function of this,due to no sharp edges on top side of ring.
Thanks Dave
