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 speed adjustment screw and a
non-adjustable idle mixture valve.
Note: Engines operated at approximately 3000 to 5000 feet
(900 to 1500 meters) above sea level may require a high alti-
tude carburetor main jet. If erratic performance is observed,
contact a Briggs & Stratton Authorized Service Dealer for cost
to install/purchase a high altitude carburetor main jet.
