Carburetor Adjustment
The carburetor on this engine is not adjustable.
Engines operated above 5000 feet (1524 meters) may
require a high altitude carburetor main jet. Contact a
Briggs & Stratton Authorized Service Dealer for high
altitude carburetor main jet information.
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.
WARNING
Combustion Deposits
We recommend that after every 100-400 hours you
have an authorized Briggs & Stratton Service Dealer
remove combustion deposits from the cylinder, cylinder
head, top of piston, and around valves.
Cleaning Debris
Daily or before every use, clean accumulated debris
from engine. Keep linkage, spring and controls clean.
Keep muffler area clean and muffler in working order.
Daily or more often, before running engine, clean
muffler area to remove all grass and combustible
debris. If engine muffler is equipped with spark arrester
screen, remove for cleaning and inspection. Replace if
damaged or plugged.
Air Cooling System
Over time debris may accumulate in cylinder cooling
fins and cannot be removed without partial engine
disassembly. We recommend that you have an
authorized Briggs & Stratton Service Dealer clean the
air cooling system at the recommended intervals.
Proper cleaning will require the removal of blower
housing and cleaning of areas shown.
Ê This prevents
overheating and engine damage.
Equally important is to keep top of engine free from
debris. See Cleaning Debris section.
Engine parts should be kept clean to reduce
the risk of overheating and ignition of accu-
mulated debris.
WARNING
Do not use water to clean engine parts. Water
could contaminate fuel system. Use a brush or dry
cloth.
