Did that also mean that the ring pins were on the intake side with the windows on the exhaust side, or was this merely that the arrow on top of the piston was engraved on the wrong side where all you need to do is just ignore the arrow as long as the windows and ring pins are both on the intake side.
I have seen the arrow marked wrong so it was easy to just not follow the arrow but to make sure that the ring pins themselves would be on the intake side.
(I hope I made that understandable, couldn't sleep again last night whilst still in recovery)...lol.
