HIGH ALTITUDE OPERATION
At high altitude, the standard carburetor air-fuel mix-
ture 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.
High altitude performance can be improved by specific
modifications to the carburetor. If you always operate
your engine at altitudes above (6,000 feet) 1,800
meters, have a engine dealer perform this carburetor
modification.
Even with carburetor modification, engine horsepower
will decrease about 3.5% for each 1,000 feet (300
meter) increase in altitude. The effect of altitude on
horsepower will be greater than this if no carburetor
modification is made. Do not operate a modified
engine below 6,000 feet.
LIFTING
The GX-271 weighs approximately 469 lbs/212 kg. A
lift bail is mounted to the machine frame and should
always be used when lifting the machine.
