Steve,
72 PSI sounds quite low for a 560 gas. I believe you should be getting about 110 PSI for all cylinders, plus or minus 10%. I would check it again. Spin the engine over several times on each cylinder so you get an accurate reading. Then, squirt about two tablespoons of 30 wt. oil in the cylinder being checked and check it again. If the reading comes up significantly (more than a couple of PSI) the rings need replacing. If unchanged, check the valves for burning and proper sealing to the head. Good luck! Phil
