Spark Plug
Replace the spark plug every 2 years or after 150 hours of use.
Recommended Spark Plug: NGK - BPR5ES
NOTICE
An incorrect spark plug can cause engine damage.
For good performance, the spark plug must be properly gapped and
free of deposits.
1. Allow the engine to cool,
disconnect the spark plug
cap, and remove any dirt
from around the spark
plug area.
2. Remove the spark plug
with a 13/16 in (21 mm)
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.
Gap: 0.028 ~ 0.031 in
(0.7 ~ 0.8 mm).
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
13/16 in (21 mm) spark plug wrench to compress the washer.
If reinstalling the old spark plug, tighten 1/8 to 1/4 turn after the
spark plug seats.
If installing a new spark plug, tighten 1/2 turn after the spark plug
seats.
Spark plug torque: 14 ft-lb (20 N·m)
NOTICE
A loose spark plug can overheat and damage the engine.
Overtightening the spark plug can damage the threads in the
cylinder head.
7. Install the spark plug cap on the spark plug.
Spark Arrester (optional part)
The spark arrester must be serviced every 100 hours to keep it
functioning as designed.
Your lawn mower engine is not factory-equipped with a spark arrester.
In some areas, it is illegal to operate an engine without a spark
arrester. Check local laws and regulations. An optional USDA
approved spark arrester is available from an authorized Honda
servicing dealer. See page 19 for part numbers.
1. Allow the engine to cool and disconnect the spark plug cap.
2. Remove the three flange bolts and the heat shield. Remove the
setscrew and the spark arrester from the muffler.
3. Check for carbon deposits on the spark arrester and the exhaust
port. Use a brush to remove any carbon deposits from the
screen. Replace the screen if it is torn or damaged.
4. Installation is the reverse of removal. Tighten all hardware
securely.
5. Reconnect the spark plug cap.
