Spark Plug Inspection

The spark plug is an important engine
component and is easy to inspect.
The condition of the spark plug can indicate the
condition of the engine.
For example, a very white center electrode
porcelain 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 a KYMCO 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
proper type.
Standard spark plug (NGK): CR7E
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)
