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 1,500 meters (5,000 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-foot) 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 1,500 meters (5,000 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.
Coat the terminals and cable ends with grease.
Connect the battery negative ( ) cable to the battery negative
( ) terminal as shown.
Connect the battery positive ( ) cable to the battery positive ( )
terminal as shown.
Connect the battery negative ( ) cable to an engine mounting
bolt, frame bolt, or other good engine ground connection.
Connect the battery positive ( ) cable to the starter solenoid
terminal as shown.
Keep all sparks, open flames, and smoking materials
away from the battery.
A battery can explode if you do not follow the correct
procedure, seriously injuring anyone nearby.
Be careful not to connect the battery in reverse polarity, as this will
short circuit the battery charging system. Always connect the
positive (
) battery cable to the battery terminal before
connecting the negative ( ) battery cable, so your tools cannot
cause a short circuit if they touch a grounded part while tightening
the positive (
) battery cable end.
