Engine Oil Recommendations

Oil is a major factor affecting performance and service life. Always
change the oil in accordance with the Maintenance Schedule
(page 11).
Recommended oil for general use: SAE 10W-30
Other viscosities shown in the chart may be used when the average
temperature in your area is within the recommended range.
The SAE oil viscosity and service category are in the API label on the
oil container. Honda recommends API service category SJ or later oil.

Air Cleaner

Clean the air filter after the first 25 hours of use. Thereafter, clean the
filter every 6 months or 50 hours of use. Clean the filter more often
when used in dusty areas. Replace the filter every 2 years or 250
hours of use. See page 11 for the complete maintenance schedule.
A properly maintained air filter will help prevent dirt from entering your
engine. Dirt entering the carburetor can be drawn into small passages
in the carburetor and cause premature engine wear. These small
passages can become blocked, causing starting or running problems.
Operating the engine without an air filter, with a damaged air filter, or
with an improperly installed air cleaner cover will allow dirt to enter the
engine, causing rapid engine wear. This type of damage is not
covered by the DISTRIBUTOR'S LIMITED WARRANTY
We recommend the use of a Honda Genuine air filter to ensure it
seals and performs as designed. Using a non-Honda air filter can
result in dirt bypassing the filter, causing damage to the engine or fuel
system.
1. Press down on the cover tabs and remove the cover.
2. Remove the filters from the air cleaner housing.

3. Inspect the filters; replace if damaged.
4. Paper Air Filter: Clean the paper filter by tapping it several times on
a hard surface to remove dirt, or blow compressed air (not
exceeding 30 psi [207 kPa]) through the air filter from the inside.
Never try to brush off dirt; brushing will force dirt into the fibers.

6. Wipe dirt from the inside of the air cleaner housing and cover using
a moist rag. Be careful to prevent dirt from entering the air duct that
leads to the carburetor.
7. Reinstall the filters, grid, and cover as shown. Be sure both tabs
are fully locked in place.

Spark Plug

Replace the spark plug every 2 years or after 250 hours of use.
Required Spark Plug: NGK - BPR6ES
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 onto the spark plug.
