Ando. first do the "dry test". Be sure the batteries are fully charged, all spark plugs removed, choke open and the throttle set to full. Now do a compression test on each cylinder. I do them twice for checking MY consistancy. That is the dry test.
Wet test is the SECOND test. Now "spray" some WD-40 or spray oil of some sort into the cylinders. Now test again while the cylinder is wet with oil. The oil will fill some of the gaps in the rings if they are worn and you should see "more compression" if the rings are bad. If the compression numbers stay the same and are low you may have valve issues.
