SPARK PLUG SERVICE
Recommended spark plug: F6RTC
1. Disconnect the spark plug cap, and remove any dirt from around the spark plug area.
2. Remove the spark plug with a spark plug wrench.
3. Inspect the spark plug. Replace it if the electrodes are worn, or if the insulator is cracked or chipped.
4. Measure the spark plug electrode gap with a suitable gauge. The gap should be 0.028~0.031 in (0.70~0.80mm).
Correct the gap if necessary, by carefully bending the side electrode.
5. Install the spark plug carefully, by hand, to avoid cross-threading.
6. After the spark plug seats, tighten with a spark plug wrench to compress the sealing washer.
If reinstalling the used spark plug, tighten 1/8-1/4 turn after the spark plug seats.
If installing a new spark plug, tighten 1 / 2 turn after the spark plug seats.
NOTICE
A loose spark plug can overhand and damage the engine.
Overtightening the spark plug can damage the threads in the cylinder head.
7. Attach the spark plug cap.
