screw thread.

only need to screw it from one eighth circle to one fourth circle after it is fixed.
19. Re-install the cap of the spark plug.
20. Reinstall the repair cover of the spark plug.
Look out
The spark plug must be fixed firmly, or else it will become very hot and
damage the generator.
Do not use the spark plug whose thermal measurement range is not
suitable.
