SPARK PLUG
Recommended Spark Plug:
The recommended spark plug is the correct heat range for normal
engine operating temperatures.
NOTICE
Incorrect spark plugs can cause engine damage.
For good performance, the
spark plug must be properly
gapped and free of deposits.
1. Disconnect the cap from
the spark plug, and
remove any dirt from the
spark plug area.
2. Use the proper size spark
plug wrench to remove
the spark plug.
3. Inspect the spark plug. Replace it if damaged, badly fouled, if the
sealing washer is in poor condition, or if the electrode is worn.
4. Measure the electrode gap with a
suitable gauge. The correct gap is
0.70 ~ 0.80 mm (0.028 ~ 0.030 in).
If adjustment is needed, correct the
gap by carefully bending the side
electrode.
5. Install the spark plug carefully, by
hand, to avoid cross-threading.
6. After the spark plug is seated,
tighten with the proper size spark
plug wrench to compress the
washer.
When installing a new spark plug, tighten 1/2 turn after the spark
plug seats to compress the washer.
When reinstalling the original spark plug, tighten 1/8 ~ 1/4 turn
after the spark plug seats to compress the washer.
NOTICE
Properly tighten the spark plug. A loose spark plug can become
very hot and can damage the engine. Overtightening the spark
plug can damage the threads in the cylinder head.
7. Attach the spark plug cap to the spark plug.
FLYWHEEL BRAKE INSPECTION
1. Remove the three flange
nuts from the recoil
starter, and remove the
recoil starter from the
engine.
2. Remove the fuel tank from
the engine without
disconnecting the fuel
tube. If the fuel tank
contains fuel, keep it level
as you remove it and set it
beside the engine in a
level position.
3. Check the brake shoe
thickness. If it is less than
3 mm, take the engine to
your authorized Honda
servicing dealer.
4. Install the fuel tank and
recoil starter, and tighten
the three nuts securely.
