4. Use a 21mm (13/16") spark plug socket to remove the spark
plug.
5. Set the new spark plug's gap to 0.70-0.80 mm (0.028 – 0.031
in). Install the correctly gapped spark plug into the cylinder
head and tighten enough to ensure the gasket compresses at
(18.0 to 21.6 Pound/Feet) (Figure 15).

3.5 VALVE CLEARANCE
• Intake — 0.15 ± 0.02mm (cold), (0.006" ± 0.0008")
• Exhaust — 0.20 ± 0.02mm (cold) (0.008" ± 0.0008")
After the first 50 hours of operation, check the valve clearance
in the engine and adjust if necessary.
Important: If feeling uncomfortable about doing this procedure or
the proper tools are not available, please take the generator to the
nearest service center to have the valve clearance adjusted. This is
a very important step to ensure longest life for the engine.
3.6 GENERAL
The generator should be started at least once every 30 days and
be allowed to run at least 30 minutes. If this cannot be done and
the unit must be stored for more than 30 days, use the following
information as a guide to prepare it for storage.
Allow unit to cool entirely before storage.
NOTE:
