Remote Control Linkage (optional part)
The throttle control lever is provided with hole for optional cable
attachment. The following illustrations show installation
examples for a solid wire cable and for a flexible, braided wire
cable. If using a flexible, braided wire cable, add a return spring as
shown.
It is necessary to loosen the throttle lever friction nut when
operating the throttle with a remote-mounted control.

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 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-300 meter 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 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.
