Removal from Storage
Check your engine as described in the BEFORE OPERATION CHECKS
section of this manual (see page 2).
If the fuel was drained during storage preparation, fill the tank with fresh
gasoline. If you keep a container of gasoline for refueling, be sure it
contains only fresh gasoline. Gasoline oxidizes and deteriorates over
time, causing hard starting.
If the cylinder was coated with oil during storage preparation, the engine
will smoke briefly at startup. This is normal.
After storage for more than 1 month, the battery had entered STORAGE
MODE (see page 2).
TRANSPORTING
If the engine has been running, allow it to cool for at least 15 minutes
before loading the engine-powered equipment on the transport vehicle.
A hot engine and exhaust system can burn you and can ignite some
materials.
Keep the engine level when transporting to reduce the possibility of fuel
leakage. Turn the fuel valve lever to the OFF position.
See Figure 2, page A-2.

Carburetor Modifications for High Altitude Operation
At high altitude, the standard carburetor air-fuel mixture will be too rich.
Performance will decrease, and fuel consumption will increase. A very
rich mixture will also foul the spark plug and cause hard starting.
Operation at an altitude that differs from that at which this engine was
certified, for extended periods of time, may increase emissions.
High altitude performance can be improved by specific modifications to
the carburetor. If you always operate your engine at altitudes above
610 meters (2,000 feet), have your servicing dealer perform this
carburetor modification. This engine, when operated at high altitude
with the carburetor modifications for high altitude use, will meet each
emission standard throughout its useful life.
Even with carburetor modification, engine horsepower will decrease
about 3.5% for each 300 meter (1,000 feet) increase in altitude. The effect
of altitude on horsepower will be greater than this if no carburetor
modification is made.
When the carburetor has been modified for high altitude operation, the air-
fuel mixture will be too lean for low altitude use. Operation at altitudes below
610 meters (2,000 feet) with a modified carburetor may cause the engine to
overheat and result in serious engine damage. For use at low altitudes, have
your servicing dealer return the carburetor to original factory specifications.
Correction
Charge the battery if the battery
indicator does not light on or flash
even the brake lever of the
equipment powered by this
engine is clutched (P.2).
Take engine to your servicing
dealer, or refer to shop manual.
Correction
Check if the connection is correct.
Take external charger to your
servicing dealer, or refer to shop
manual.
Take engine to your servicing
dealer, or refer to shop manual.
