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. If
necessary, reset the gap (See Specifications).
5.
Correct the gap by carefully bending the side
electrode. Check the gap after each adjustment.
6.
Install the spark plug by hand until hand-tight. Avoid
cross-threading the spark plug.
