Carburetor adjustment for high altitude
operation
The altitude has an effect on the engine performance
and emissions. If the engine is always operated at
altitudes higher than 1500 m/5000 ft, it is necessary to
adjust the carburetor. Let your servicing dealer do the
necessary adjustments.
CAUTION: Do not operate the engine on
lower altitudes if the carburetor is adjusted

damage. Let your servicing dealer adjust the
carburetor to factory specifications.
Emission control system
This engine uses lean carburetor adjustments and other
systems to decrease the emissions of dangerous
materials in the exhaust fumes. The air intake, the fuel
system and the exhaust system are parts of the
emission control system. If modifications are done to the
emission control system, the emissions increase.
If modifications are done to the speed adjustment
mechanism or governor linkage, the engine does not
operate as intended. This can also cause increased
emissions.
It is necessary to use original spare parts to make sure
that the emission control system operates correctly.
The engine must be examined and repaired by an
approved servicing dealer if 1 or more of these problems
occur:
• The engine is not easy to start or stops again after a
