Have you squirted some oil down the cylinder .. then re-done the comp. test ?

If it has a broken ring , stuck ring or worn rings etc.... then , after the oil squirt , the compression will come up , it seals the rings to some degree .

If the compression doesn't change , then you most likely have a leaky valve seat .

But before pulling the head off, do the valve tappet adjustment , it might be just a tappet nut come loose holding the valve open ?
