Cleaning

1. Tap the filter several times on a hard surface to remove dirt, or
blow compressed air not exceeding 30 psi (207 kPa) through the
filter from the clean side that faces the engine. Never try to brush
off dirt. Brushing will force dirt into the fibers.
2. Wipe dirt from the air cleaner body [4] and cover using a moist rag.
Be careful to prevent dirt from entering the air duct [5] that leads to
the carburetor.
SPARK PLUG
See Figure 5
page
3.
,
Recommended Spark Plug:
NGK - BPR6ES
Pressure washer applications
NGK - BPR5ES
All other applications
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 [1] to remove the spark
plug.
3. Inspect the spark plug. Replace it if damaged, badly fouled, if the
sealing washer [2] is in poor condition, or if the electrode is worn.
4. Measure the electrode gap with a suitable gauge. The correct gap
is 0.028 ~ 0.030 in (0.70 ~ 0.80 mm). 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 (if equipped)
See Figures 6, 7,
page
3.
Start the engine outdoors. Move the throttle lever to the FAST position
and release the flywheel brake lever; the engine should stop quickly.
1. Remove the three flange nuts [1] from the recoil starter [2], and
remove the recoil starter from the engine.
2. Remove the fuel tank [3] from the engine without disconnecting the
fuel tube [4]. 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 [5] 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.
