Spark plug service (see fig.
)
DO NOT check for spark
with spark plug removed.
Use only Briggs & Stratton
Spark Tester
for spark.
DO NOT crank engine with spark plug removed. If
engine is flooded, place throttle in FAST and crank until
engine starts.
Ë
Spark plug gap should be .76 mm or 0.030 in.
Replace spark plug every 100 hours or every season,
whichever occurs first. Spark tester and spark plug
wrench are available from any Authorized Briggs &
Stratton Service Dealer.
Note: In some areas, local law requires using a resistor
spark plug to suppress ignition signals. If this engine
was originally equipped with resistor spark plug, use
same type of spark plug for replacement.
Keep engine clean (see fig.
)
Periodically remove grass and chaff build-up from
engine. Clean finger guard. Do not spray engine with
water to clean because water could contaminate fuel.
Clean with a brush or compressed air.
Note: On string trimmer applications, clean accumu-
lated debris at each refueling, sooner if needed
Accumulation of debris around muf-
Ì
fler could cause a fire. Inspect
and clean before every use.
If muffler is equipped with spark arrester screen,
remove spark arrester screen for cleaning and inspec-
tion. Replace if damaged.
Note: Over time debris may accumulate in cylinder
cooling fins and cannot be observed without partial
engine disassembly. For this reason, we recommend
that you have an authorized Briggs & Stratton Service
Dealer clean the air cooling system per recommended
intervals. (See Maintenance Schedule below.) Equally
important is to keep top of engine free from debris. (See
Keep engine clean above.)

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.
Note: If stabilizer is not used or if engine is operating on
gasoline containing alcohol, e.g. gasohol, remove all fuel
from tank and run engine until it stops from lack of fuel.
1. While engine is still warm, drain oil from crank-
case. Refill with fresh oil of recommended SAE

viscosity grade. (see fig. )
2. Remove spark plug and pour about 15 ml (1/2
oz.) of engine oil into cylinder. Replace spark plug
and crank slowly to distribute oil.
3. Clean grass and chaff from cylinder and cylinder
head fins, under finger guard and around muffler.
4. Store in a clean and dry area, but NOT near a
stove, furnace or water heater which uses a pilot
light or any device that can create a spark.
