PERIODIC MAINTENANCE 2-7
SPARK PLUG
Standard spark plug: NGK CR6HSA
CARBON DEPOSIT
Inspect for a carbon deposit on the spark plug bases.
If carbon is present, remove carbon with a spark plug cleaning
machine or by carefully using a pointed tool.
SPARK PLUG GAP
Measure for the spark plug gap using the thickness gauge.
Adjust to within the specified range if the gap is out of the speci-
fication.
Spark plug gap: 0.6 – 0.7 mm (0.024 – 0.028 in)
09900-20803: Thickness gauge
CONDITION OF ELECTRODE/INSULATOR
Check the electrode and insulator condition.
If the electrode is extremely worn or burnt, replace the spark
plug.
If the spark plug has a broken insulator, damaged threads, etc.,
replace the spark plug.
Spark plug: 11 N·m (1.1 kg-m, 8.0 lb-ft)
• Inspect every 100 hours (6 months).
• Replace every 200 hours (12 months).
Only resistor (R) type spark plugs must be used with
this engine. Using a non-resistor spark plug will cause
ignition system malfunctions.
Gap
Confirm the thread size and reach when replacing the
plug. If the reach is too short, carbon will be deposited
on the threaded portion of the plug hole resulting in
possible engine damage.
