IMPORTANT NOTE - Time intervals shown are maximum. Actual use and
your experience will determine the frequency of required maintenance.
MAINTENANCE PROCEDURE NOTES:
* Replacement is recommended based on the finding of damage or wear
during inspection.
Carburetor Adjustment
Every unit is run at the factory and
the carburetor is set in compliance
with Emission Regulations. In
addition, the carburetor is equipped
with “H” (High Speed) and “L” (Low
Speed) needle adjustment limiters
that prevent settings outside
acceptable limits.
Engine Break-In
New engines must be operated a
minimum duration of two tanks of fuel break-in before carburetor
adjustments can be made. During the break-in period your engine
performance will increase and exhaust emissions will stabilize. Idle speed
can be adjusted as required.
High Altitude Operation
This engine has been factory adjusted to maintain satisfactory starting and
durability performance up to 335m (1,100 ft.) above sea level (ASL) (96.0
kPa). To maintain proper engine operation above 335m (1,100 ft.) ASL the
carburetor may
need to be adjusted by an authorized service dealer.
If the engine is adjusted for operation above 335 m (1,100 ft.) ASL,
the carburetor must be re-adjusted when operating the engine below
335 m (1,100 ft.) ASL, otherwise severe engine damage may result.
