A. CARBURETOR ADJUSTMENT.
The carburetor is preset at the factory. This is the
optimum setting under the barometric pressure and
climatic conditions at the factory and is suitable for
most operating sites.
It ensures that your machine will run smoothly, be
fuel efficient, operate reliably and produce low
emissions.
If the engine runs unsatisfactorily at high altitudes
or at sea level, slight readjustment of the carburetor
may be necessary:

Every unit is run at the factory and the carburetor is
set in compliance with EPA. In addition, the
carburetor is equipped with H and L needle
adjustment limiters that prevent settings outside
acceptable limits.
