MAINTENANCE
High Altitude Operation
This engine has been factory adjusted to maintain satisfactory starting, and
durability performance up to 330 m (1100 ft.) above sea level (ASL) (96.0
kPa). To maintain proper engine operation above 330 m (1100 ft.) ASL the
carburetor may need to be adjusted by an authorized service dealer.
If the engine is adjusted for operation above 330 m (1100 ft.) ASL, the
carburetor must be re-adjusted when operating the engine below
330 m (1100 ft.) ASL, otherwise severe engine damage may result.
Note: Every unit is run at the
factory and the carburetor
is set in compliance with
emission regulations.
Carburetor adjustments,
other than idle speed,
must be performed by an
authorized dealer.
1. Check idle speed and reset if
necessary. If a tachometer is
available, idle speed screw (A)
should be set to the
specifications found on
"Specifications" page of this
manual. Turn idle screw (A)
clockwise to increase idle
speed; counterclockwise to decrease idle speed.
