SPARK PLUG
Recommended Spark Plug:
The recommended spark plug has the correct heat range for
normal engine operating temperatures.
Incorrect spark plugs can cause engine damage.
If the engine has been running, let it cool before servicing the spark plugs.
For good performance, the spark plugs must be properly gapped
and free of deposits.
1. Disconnect the spark plug caps, and remove any dirt from
around the spark plug area.
2. Remove the spark plugs with a 13/16-inch spark plug wrench.

3. Inspect the spark plugs.
Replace them if damaged,
badly fouled, if the sealing
washer is in poor condition,
or if the electrode is worn.
4. Measure the spark plug
electrode gaps with a
wire-type feeler gauge.
Correct the gap, if
necessary, by carefully
bending the side electrode.
The gap should be:
0.7–0.8 mm
(0.028–0.031 in)
5. Install the spark plug
carefully, by hand, to avoid
cross-threading.
6. After the spark plug is seated, tighten with a 13/16-inch
spark plug wrench to compress the sealing washer.
When installing a new spark plug, tighten 1/2 turn after the
spark plug seats to compress the washer.
When reinstalling a used spark plug, tighten 1/8–1/4 turn
after the spark plug seats to compress the washer.
TORQUE: 18.0 N∙m (1.8 kgf∙m, 13 lbf∙ft)
A loose spark plug can overheat and damage the engine. Overtightening
the spark plug can damage the threads in the cylinder head.
7. Attach the spark plug caps to the spark plugs.

In Europe and other countries where the machinery directive
2006/42/EC is enforced, this cleaning should be done by your
servicing dealer.
Your engine is not factory-equipped with a spark arrester. The
spark arrester is optional part. In some areas, it is illegal to
operate an engine without a spark arrester. Check local laws and
regulations. A spark arrester is available from authorized Honda
servicing dealers.
The spark arrester must be serviced every 100 hours to keep it
functioning as designed.
If the engine has been running, the muffler will be hot. Allow it to
cool before servicing the spark arrester.
Spark Arrester Cleaning & Inspection
1. Remove the spark arrester:
Remove the special screw from the muffler and remove the
spark arrester.

2. Use a brush to remove carbon deposits from the spark
arrester screen. Be careful to avoid damaging the screen.
The spark arrester must be free of breaks and holes. Replace
the spark arrester if it is damaged.
3. Install the spark arrester and muffler protector in the reverse
order of disassembly.
