and wring the excess oil out of the filter.
5.13 Spark Plug
a) Remove the spark plug and inspect it with a
spark plug wrench each time you change the oil;
If possible, check the spark plug gap (the area
between the two electrodes)with a wire feeler
gauge, and this specification should be
0.6-0.7mm.
NOTE: The electrodes should be kept clean and
free of carbon. The presence of carbon or excess
oil will greatly deter the proper engine
performance.
b) Before installing the spark plug, apply some graphite grease on the threads if
possible to ensure the easy removal next time when the spark plug needs
inspection.
c) It is advisable to replace the spark plug at least once a year to insure the easy
starting and good engine performance.
