Take the plugs out and squirt some mystery oil in all the cylinders. Turn it over by hand on the crank pulley. Might have to let it sit a bit with the oil in it. If that doesn't work, rebuild time. You rings are junk. Should add also that you should remove the outdrive also. That could stop a motor from turning.

Do i need to remove the exhaust logs to get to the plugs? I assume I do since i cannot even see the plugs... wow how do these things come off...
