SPARK PLUG
A spark plug with heavy carbon deposits will not produce
strong sparks. Hence, as per schedule or, as and when
necessary, clean the carbon deposits from the spark plug
with a small wire brush or a spark plug cleaning tool.
Readjust the spark plug gap to 0.6 ~ 0.8 mm using a feeler
gauge / wire gauge. Replace the spark plug every 12000
km
. The carbon deposits on the porcelain tip and its colour
tells you whether the combustion of the engine is good or
not.
If the colour of tip is white or glazed, dry black or wet black
then have the vehicle checked by TVS Motor Company
