Inspecting, Replacing or Cleaning the
Spark Plug
The spark plug should be checked after every 100
hours of operation or every six months.
To replace or clean the spark plug:
1.Disconnect the spark plug wire by pulling it off the
spark plug.
2.Using provided spark plug wrench , remove the
spark plug by turning it counter-clockwise. If there is a
carbon sediment build-up, remove it. If there is too
much carbon sediment, replace the spark plug.
3.Check the gap with a wire gauge. If necessary,
reset the gap to 0.7-0.8 mm. Install and tighten the
spark plug to the recommended torque–180 lb-in (20
Nm).
4.Reinstall the spark plug wire and protection cage in
reverse order.
NOTE:
In some areas, local law requires using a
resistor spark plug to suppress ignition signals. If this
engine was originally equipped with a resistor spark
plug, use the same type for replacement.
