CARBURETOR ADJUSTMENT
WARNING
The manufacturer of the equipment on which this
engine is installed specifies top speed at which the
engine will be operated. DO NOT EXCEED this speed.
Differences in fuel, temperature, altitude or load may
require minor carburetor adjustment. Air cleaner and air
cleaner cover must be assembled to carburetor before
starting engine.
The carburetor on this engine is low emission. It is
equipped with an idle mixture valve with a limiter (see
inset), which allows some adjustment, and an idle speed
adjustment screw. DO NOT remove limiter caps. DO NOT
force beyond limits.
