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.
A primer equipped engine idles down only about 600 to
900 rpm below top speed, which accounts for the
higher than expected idle speed.
Air/fuel mixture is not adjustable.
See an Authorized Briggs & Stratton Dealer for
carburetor adjustment of a choke equipped engine.
