I have, but that was due to rust in the bore. I'm just skeptical that rings became stuck or broken in both sides... But I'm also skeptical of the low compression, when I can see the bore and the piston, and visually the bore looks nice and not all worn out, and there's no scoring at all. All signs point to some issue with the rings, whether stuck, broken, or worn... At this point the only way to know for sure is to pull the pistons out and looking at the rings.
