6.6 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. Move the fuel valve lever to the OFF position.
7 Taking care of unexpected problems
Engine will not start Possible cause Correction

8.2 Carburetor modification 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 5,000 feet (1,500 meters), 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 1,000-foot (300 meter) increase in altitude, the
effect of altitude on horsepower will be greater than this if no carburetor modification is made.
NOTE
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 5,000feet (1,500 meters) 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.
