Air Cooling System
Over time debris may accumulate in cylinder cooling fins and
cannot be observed without partial engine disassembly. For
this reason, we recommend you have an authorized Briggs &
Stratton service dealer clean the cooling system per
recommended intervals (see Maintenance Schedule in
beginning of Maintenance section). Equally important is to
keep top of engine free from debris. See Clean Debris.
Carburetor Adjustment
The carburetor on this engine is low emission. It is equipped
with a non-adjustable idle mixture valve. Top speed has been
set at the factory. If adjustment is required, see an
authorized Briggs & Stratton service dealer.
