Default RE: spark plug compression leak

The Zenoah glow plug adapter has a taper for a taper seat; no gasket. His engine probably had a gasketed spark plug.

You can try adding a gasket. Another way would be to machine a short taper in your head to match the taper of the glow plug adapter. I don't recommend any sealer...
