CAUTION:
A dirty air filter will restrict air flow to the carburetor, reducing engine
performance.
If you operate the engine in very dusty areas, clean the air filter more often than specified in the
MAINTENANCE SCHEDULE.
INSPECTION
1. Press the latch tabs on the air cleaner cover or remove the cap nuts, remove the cover,
and check the filter to be sure it is clean and in good condition.
2. Reinstall the filter and air cleaner cover.
Cleaning
1. Tap the outer filter several times on a hard surface to remove dirt, or blow compressed air
(not exceeding 30 psi [207kPa, 2.1kg/cm
2
]) 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. If the outer filter is very dirty, replace it.
3. 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.
CAUTION:
Operating the engine without an air filter, or with a damaged air filter, will allow
dirt to enter the engine, causing rapid engine wear. This type of damage is not covered by the
Distributor’s Limited Warranty.
SPARK PLUG SERVICE
Recommended spark plug: F7RTC or equivalent.
CAUTION:
An incorrect spark plug can cause engine damage.
1. Disconnect the spark plug cap, and remove any dirt from
around the spark plug area.
2. Remove the spark plug with a 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.
