4. With the engine in a level position, fill to the upper limit mark 

(bottom edge of the oil fill hole) on the dipstick with the 
recommended oil (see page 5) Do not overfill.

5. Reinstall the oil filler cap/dipstick securely.

A dirty air cleaner will restrict air flow to the carburetor and cause poor 
engine performance. Inspect the filter each time the engine is 
operated. You will need to clean the filter more frequently if you 
operate the engine in very dusty areas.

Operating the engine without an air filter, or with a damaged filter, will 
allow dirt to enter the engine, causing rapid engine wear. This type of 
damage is not covered under the Distributor’s Limited Warranty (see 
page 11).

1. Press the latch 

tabs on the top of 
the air cleaner 
cover, and remove 
the cover. Check 
the filter to be sure 
it is clean and in 
good condition.

2. Reinstall the filter 

and air cleaner 
cover.

1. Tap the filter several times on a hard surface to remove dirt, or 

blow compressed air [not exceeding 30 psi (207 kPa, 2.1 kg/cm²)] 
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 and cover using a moist rag. Be 

careful to prevent dirt from entering the air duct that leads to the 
carburetor.

The recommended spark plug is the correct heat range for normal 
engine operating temperatures.

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 
0.028 - 0.031 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.

7. When installing a new spark plug, tighten 1/2 turn after the spark 

plug seats to compress the washer.

8. When reinstalling the original spark plug, tighten 1/8 - 1/4 turn after 

the spark plug seats to compress the washer.

9. Attach the spark plug cap to the spark plug.

In some areas, it is illegal to operate an engine without a USDA 
(United States Department of Agriculture)-qualified spark arrester. 
Check local laws and regulations. A USDA-qualified spark arrester is 
available from an authorized Honda servicing dealer.

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.

1. Remove the three 

6 mm bolts from the 
muffler protector, and 
remove the muffler 
protector.

2. Remove the two special 

screws from the spark 
arrester, and remove the 
spark arrester from the 
muffler.

1. Use a brush to remove carbon 

deposits from the spark arrester 
screen. Be careful not to damage 
the screen. Replace the spark 
arrester if it has breaks or holes.

2. Install the spark arrester in the 

reverse order of removal.
