SPARK PLUG INSPECTION
The spark plug is an important engine component and is
easy to inspect. The condition of the spark plug can

color could indicate an intake air leak or carburet problem
for that cylinder. Do not attempt to diagnose such
problems yourself.
Instead, take the machine to our dealer.
You should periodically remove and inspect the spark
plug because heat and deposits will cause the spark plug
to slowly break down and erode.
If electrode erosion becomes excessive, you should
replace the spark plug with one of the
Standard spark plug: D8REA
Before installing the spark plug, measure the electrode
gap with a feeler gauge and adjust to specification.
Spark plug gap:
0.6~0.7 mm (0.024~0.028 in)
