Carburetor adjustments
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
a non adjustable idle mixture jet (see inset) and an idle speed
adjustment screw. Only the idle speed screw is adjustable.
Governed idle has been set to 1750 rpm at the factory.
Adjustments
Start engine and warm up approximately 5 minutes before
adjusting. With engine running, place throttle control in SLOW
position. Rotate carburetor throttle lever against Idle speed
screw and hold. Adjust idle speed screw to obtain 1400 rpm.
