may clog engine's air cooling system, especially after
prolonged operation. Internal cooling fins and surfaces
may require cleaning to prevent overheating and engine
damage. Remove blower housing and clean as shown.
Adjustments
Carburetor adjustment
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.
See an Authorized Briggs & Stratton Dealer for
carburetor adjustment.
Note: Engines operated at about 900 meters or higher
(3000 feet) above sea level may require a high altitude
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, if available.

Storage
1. Drain and disconnect hoses. Flush pump with
clean water.
2. Change engine oil. See Maintenance.
3. Remove spark plug and pour about 15 ml (1/2
oz.) of oil into cylinder. Pull rope handle slowly,
which will crank engine over slowly to distribute
oil. Replace spark plug.
4. Store in a clean and dry area.
Equipment stored over 30 days need to be protected or
drained of fuel to prevent gum from forming in fuel
system or on essential carburetor parts.
For engine protection, we recommend use of Briggs &
Stratton Fuel Stabilizer available from an Authorized
Briggs & Stratton Service Dealer. Mix stabilizer with fuel
in fuel tank or storage container. Run engine for a short
time to circulate stabilizer through carburetor. Engine
and fuel can be stored up to 24 months.
