could still be an issue with the motor having so few miles but most rings will seal up fairly well by then. i would pull the plugs and pump air into the cylinders and listen at the dipstick for air escaping. if it sounds like a slow tire leak you just might need some more run time but if it sounds like a lot of air is escaping you got yourself a ring problem. oh yeah and of course make sure you rotate the motor so both the valves are shut. i use my compression tester hose to put air in the cylinders just remove the one way valve from it and the other end should have a standard air hose connector.
