Good idea on the ring "end gaps". I’ll try to get a ring in the bore and
measure the gap, but with the way this power head is built, it may be
hard to get a measurement with the ring at the top of the bore.
It’s "headless" and the jug and crankcase is all one casting.
This piston comes out of the bottom of the crankcase after the
crankshaft is removed.
It’s the type of piston that has all three rings pinned with the end gaps
lined up in a row……… that never made sense to me!
I remember reading that about honing / roughing up the rings on that
other thread…… not sure I’m ready for that one yet. 😕
