    Just a shot in the dark..Doses it have valve covers on it to access the valve?
    If so Turn motor by hand and watch for movement.
    Can You see inside the plug hole and rotate the motor by hand to see if the vale move?

    Engine numbers are always useful-

    What did the old spark plug look like? IF it was all crudded up, I would tend to think that possibly the head gasket may be blown.
