fore you examine the spark plug, the centre electrode may be dark brown or
even black. For all the different applications that the engine has been tested
for, the recommended spark plug Nippondenso W22MP-U has proven to be
the best, and no ”hotter” or ”cooler” plug is recommended.
The normal service life of a spark plug is 200 - 300 hours. However, we
recommend that you have extra spark plugs available, as e.g. repeated
attempts to start a flooded engine (too rich fuel mixture) can destroy a spark
plug.
