[4] CHECK POINTS OF EVERY 100 HOURS

Cleaning Spark Plug (If Necessary)
1. Remove the spark plug, and remove carbon from the electrode
with a wire brush or other tools.
2. After cleaning, be sure to adjust for proper clearance.
IMPORTANT
• If the spark plug electrode or its insulator is soiled or is
covered with deposited carbon, it may cause engine
trouble.
Adjusting Spark Plug (If Necessary)
1. Measure the spark plug gap with a feeler gauge, and repair or
replace the spark plug if the measured gap differs from the
factory specification.
2. Replace the spark plug if the electrode or the insulator is
deformed or cracked.
3. Tighten the spark plug with a plug wrench.
IMPORTANT
• If the spark plug electrode or its insulator is soiled or is
covered with deposited carbon, it may cause engine
trouble.
(When reassembling)
• Put the high tension cord cap inside the spark plug terminal
firmly.
• Make sure that the cylinder number is corresponding to the high
tension cord number.
• Wrong connection causes high temperature on catalytic
muffler/converter.
