2) Carbon fouled:
Dry fluffy carbon deposits on insulator and elec-
trode are mostly caused by slow speed driving in
the city, weak ignition, too rich fuel mixture and dirty
air cleaner.
3) Oil fouled:
Wet black deposits show oil entrance into the com-
bustion chamber through worn rings and pistons or
excessive clearance between valve guides and
stems.
4) Overheating:
White or light gray insulator with black or brown
spots and bluish burnt electrodes indicate engine
overheating. Moreover, the appearance results
from incorrect ignition timing, loose spark plugs,
wrong selection of fuel, hotter range plug, etc.
D: ADJUSTMENT
Clean the spark plugs using a wire brush. Clean
and remove the carbon or oxide deposits. But do
not wear away ceramic insulator at this time. If de-
posits are too stubborn, replace the spark plugs.
After cleaning the spark plugs, measure the spark
plug gap using a gap gauge.
NOTE:
Do not use a plug cleaner because the spark plugs
are applied with iridium tip.

0.7 — 0.8 mm (0.028 — 0.031 in)

engine oil level is below “L” line, add oil to bring the
level up to “F” line.
5) After turning off the engine, wait a few minutes
for the oil to return to the oil pan before checking
the level.

5) Using engine oil of proper quality and viscosity,
fill engine oil through the oil filler duct to the upper
level on level gauge. Make sure that the vehicle is
parked on a level surface when checking oil level.
Recommended oil:
