7.4 SPARK PLUG MAINTENANCE
NOTE
Do NOT rinse spark plug in water. Follow guidelines and be careful not
to overtighten the spark plug.
Recommended spark plug: F7RTC
Check the spark plug gap and clean the carbon deposits at the bottom of the spark
plug.
Tighten 3/8 TO 1/2 turn when installing a new spark plug.
Tighten 1/8 TO 1/4 turn when re-installing an old spark plug.
1. Make sure the engine has cooled down.
2. Remove the spark plug cap by pulling it away from the engine.
3. Remove the spark plug with the included spark plug wrench.
4. Visually inspect the spark plug. Replace with a new one if the insulation is
cracked or chipped. Clean with a wire brush if the spark plug is reused.
5. Measure the spark plug gap with a feeler gauge. The normal value is: 0.6-
0.8mm (0.024- 0.032in). Adjust the gap by carefully bending the electrode.
6. Carefully reinstall the spark plug by hand, to avoid cross-threading. A new
spark plug should be tightened 3/8 to 1/2 turn with a wrench. A used spark
plug should be tightened 1/8 to 1/4 turn with wrench.
7. Reinstall the spark plug cap.
NOTE
The spark plug must be securely tightened or it could cause the spark
plug to heat up enough to damage the engine.
Never use a spark plug with an improper heat range.
