REPLACING THE SPARK PLUG

NOTICE! Using an incorrect spark plug can cause engine damage. Only
replace a spark plug with a model recommended by the manufacturer.
The spark plug must be properly gapped and free of deposits for the
best performance. Check local bylaws to see if a resistor spark plug is
required to suppress ignition signals. Replace the included spark plug
with a resistor spark plug if required.
1. Remove any dirt from around the spark plug area.
2. Unclip the spark plug lead and remove the spark plug with a
spark plug wrench. This will have a rubber pad inside the
socket to protect the spark plug's ceramic coating.
3. Inspect the spark plug. Replace it if damaged, badly fouled, the
sealing washer is in poor condition or the electrode is worn.
4. Check the gap with a spark plug gauge
as shown in Figure 6. If necessary,
reset the gap (See Specifications).
a. Correct
bending the side electrode. Check
the gap after each adjustment.
5. Install the spark plug carefully by hand to avoid
cross threading.
6. Tighten the spark plug to the recommended torque until the gasket
is compressed. See Specifications for the correct torque rating.
7. Reconnect the spark plug lead to the spark plug.
