rings move

do the piston rings move around the piston or do they stay put?

like up and down or twisting?

im pretty sure its ok if it twists(minimally) but if its going up and down im sure it would break the seal and lose performance..... this is all from my knowledge on 2cycle motors though, i may be wrong.

With the exception of two strokes which have pins to prevent it, pistons rings can rotate.
