•Do not use gasoline which contains Methanol.
•Do not mix oil with gasoline.
•For engine protection use Briggs & Stratton
Gasoline Additive available from your Authorized
Briggs & Stratton Dealer.
•This engine is certified to operate on gasoline.
Exhaust Emission Control System: EM (Engine
Modifications).
Adding Fuel
[1] Remove cap. Fill tank to approximately 1-1/2
inches below top of neck to allow for fuel
expansion. Be careful not to overfill.
Briggs & Stratton Smart-fill fuel can fills to the
correct level and automatically shuts off, reducing
spills and emissions.
[2] Replace cap before starting.
Fuel Fill
Neck
Some fuels, called oxygenated or reformulated
gasoline, are gasoline blended with alcohols or
ethers. Excessive amounts of these blends can
damage the fuel system or cause performance
problems. If any undesirable operating
symptoms occur, use gasoline with a lower
percentage of alcohol or ether.
CAUTION
•Turn engine OFF and let engine
cool at least 2 minutes before
removing gas cap.
•Fill fuel tank outdoors or in
well-ventilated area.
•Do not overfill fuel tank. Fill tank to
approximately 1-1/2 inches below
top of neck to allow for fuel
expansion.
•If fuel spills, wait until it evaporates
before starting engine.
•Keep gasoline away from sparks,
open flames, pilot lights, heat, and
other ignition sources.
•Check fuel lines, tank, cap, and
fittings frequently for cracks or
leaks. Replace if necessary.

Stratton Service Dealer for all maintenance and service
of the engine and engine parts. Use only genuine
Briggs & Stratton parts.
This is a single cylinder, L-head, air-cooled engine. It is
a low emissions engine.
In the state of California, model 90000 / 100000
engines covered in this manual are certified by the
California Air Resources Board to meet emissions
standards for 125 hours. Such certification does not
grant the purchaser, owner or operator of this engine
any additional warranties with respect to the
performance or operational life of this engine. This
engine is warranted solely according to the product and
emissions warranties stated elsewhere in this manual.

Technical Information
Engine Power Rating Information
The gross power rating for individual gas engine models is
labeled in accordance with SAE (Society of Automotive
Engineers) code J1940 (Small Engine Power & Torque Rating
Procedure), and rating performance has been obtained and
corrected in accordance with SAE J1995 (Revision 2002-05).
Actual gross engine power will be lower and is affected by,
among other things, ambient operating conditions and
engine-to-engine variability. Given both the wide array of
products on which engines are placed and the variety of
environmental issues applicable to operating the equipment,
the gas engine will not develop the rated gross power when
used in a given piece of power equipment (actual “on-site” or
net horsepower). This difference is due to a variety of factors
including, but not limited to, accessories (air cleaner, exhaust,
charging, cooling, carburetor, fuel pump, etc.), application
limitations, ambient operating conditions (temperature,
humidity, altitude), and engine-to-engine variability. Due to
manufacturing and capacity limitations, Briggs & Stratton may
substitute an engine of higher rated power for this Series
engine.
Emission Information
Engines that are certified to meet the California Air Resources
Board (CARB) Tier 2 Emission Standards must display
information regarding the Emissions Durability Period and the
Air Index. Briggs & Stratton makes this information available to
the consumer on our emission labels. The engine emission
label will indicate certification information.
The Emissions Durability Period describes the number of
hours of actual running time for which the engine is certified to
be emissions compliant, assuming proper maintenance in
accordance with the Operating & Maintenance Instructions.
The following categories are used:
Moderate:
Engine is certified to be emission compliant for 125 hours of
actual engine running time.
Intermediate:
Engine is certified to be emission compliant for 250 hours of
actual engine running time.
Extended:
Engine is certified to be emission compliant for 500 hours of
actual engine running time. For example, a typical walk-behind
lawn mower is used 20 to 25 hours per year. Therefore, the
Emissions Durability Period of an engine with an
intermediate rating would equate to 10 to 12 years.
Certain Briggs & Stratton engines will be certified to meet the
United States Environmental Protection Agency (USEPA)
Phase 2 emission standards. For Phase 2 certified engines,
the Emissions Compliance Period referred to on the Emissions
Compliance label indicates the number of operating hours for
which the engine has been shown to meet Federal emission
requirements.
For engines less than 225 cc displacement.
Category C = 125 hours
Category B = 250 hours
Category A = 500 hours
For engines of 225 cc or more displacement.
Category C = 250 hours
Category B = 500 hours
Category A = 1000 hours.

Maintenance
Regular maintenance will improve the performance and
extend the life of the engine. See any Authorized Briggs
& Stratton Dealer for service. Use only genuine
Briggs & Stratton parts. Other parts may notperform as well, may damage the engine, and may
result in injury. In addition, use of other parts may void
your warranty.
Emission Control
Maintenance, replacement or repair of the emission
control devices and systems may be performed by
any nonroad engine repair establishment or
individual. However, to obtain no charge repairs under
the terms and provisions of the Briggs & Stratton
warranty statement, any service or emission control
part repair or replacement must be performed by a
factory authorized dealer.
Unintentional sparking can result
in fire or electric shock.
Fire or explosion can cause
severe burns or death.
Unintentional start-up can result
in entanglement, traumatic
amputation, or laceration.
Before performing adjustments or
repairs:
•Disconnect spark plug wire and
keep it away from spark plug.
•Disconnect battery at negative
terminal (only engines with electric
start).
•Do not strike the flywheel with a
hammer or hard object because
the flywheel may later shatter
during operation.
•Do not tamper with governor
spring, links or other parts to
increase engine speed.
When testing for spark:
•Use approved spark plug tester.
•Do not check for spark with spark
plug removed.

Storage
Engines stored over 30 days need special attention.
[1] To prevent gum from forming in fuel system or on
essential carburetor parts:
a) if fuel tank contains oxygenated or reformulated
gasoline (gasoline blended with an alcohol or an
ether), run engine until it stops from lack of fuel,
or b) if fuel tank contains gasoline, either run engine
until it stops from lack of fuel, or add a gasoline
additive to the gas in the tank. (See parts list.
Single-use pouches of gas additive are available
from your service dealer.) If you use a gas additive,
run the engine for several minutes to circulate the
additive through the carburetor. Then, engine and
fuel can be stored up to 24 months.
[2] While engine is still warm, change oil.
[3] Remove spark plug and pour about 1/2 oz. (15 ml)
of engine oil into cylinder. Replace spark plug and
crank slowly to distribute oil.
[4] Clean engine of surface debris, chaff or grass.
[5] Store in a clean, dry area. Do not store in same
area as a stove, furnace, water heater, or other
appliance that uses a pilot light or has a device
that can create a
spark.
When Transporting Equipment:
•Transport with fuel tank EMPTY
or with fuel shut-off valve OFF.
When storing gasoline or
equipment with fuel in tank:
•Store away from furnaces,
stoves, water heaters, or other
appliances that have a pilot light
or other ignition source because
they can ignite gasoline vapors.

							18
Briggs & Stratton welcomes warranty repair and
apologizes to you for being inconvenienced. Any
Authorized Service Dealer may perform warranty
repairs. Most warranty repairs are handled routinely,
but sometimes requests for warranty service may not
be appropriate. For example, warranty would not apply
if engine damage occurred because of misuse, lack of
routine maintenance, shipping, handling, warehousing
or improper installation. Similarly, warranty is void if
the serial number of the engine has been removed or
the engine has been altered or modified.
If a customer differs with the decision of the Service
Dealer, an investigation will be made to determine
whether the warranty applies. Ask the Service Dealer
to submit all supporting facts to his Distributor or the
Factory for review. If the Distributor or the Factory
decides that the claim is justified, the customer will be
fully reimbursed for those items that are defective. To
avoid misunderstanding which might occur between
the customer and the Dealer, listed below are some of
the causes of engine failure that the warranty does not
cover.
Normal wear:
Engines, like all mechanical devices, need periodic
parts service and replacement to perform well.
Warranty will not cover repair when normal use has
exhausted the life of a part or an engine.
Improper maintenance:
The life of an engine depends upon the conditions
under which it operates, and the care it receives.
Some applications, such as tillers, pumps and rotary
mowers, are very often used in dusty or dirty
conditions, which can cause what appears to be
premature wear. Such wear, when caused by dirt,
dust, spark plug cleaning grit, or other abrasive
material that has entered the engine because of
improper maintenance, is not covered by warranty.
This warranty covers engine related defective
material and/or workmanship only
, and not
replacement or refund of the equipment to which
the engine may be mounted. Nor does the
warranty extend to repairs required because of:
1. PROBLEMS CAUSED BY PARTS THAT ARE
NOT ORIGINAL BRIGGS & STRATTON PARTS.
2. Equipment controls or installations that prevent
starting, cause unsatisfactory engine performance,
or shorten engine life. (Contact equipment
manufacturer.)
3. Leaking carburetors, clogged fuel pipes, sticking
valves, or other damage, caused by using
contaminated or stale fuel. (Use clean, fresh,
lead-free gasoline and Briggs & Stratton Fuel
Stabilizer, Part No. 5041.)4. Parts which are scored or broken because an
engine was operated with insufficient or
contaminated lubricating oil, or an incorrect grade
of lubricating oil (check oil level daily or after every
8 hours of operation. Refill when necessary and
change at recommended intervals.) OIL GARD®
may not shut down running engine. Engine
damage may occur if oil level is not properly
maintained. Read Operating & Maintenance
Instructions.
5. Repair or adjustment of associated parts or
assemblies such as clutches, transmissions,
remote controls, etc., which are not manufactured
by Briggs & Stratton.
6. Damage or wear to parts caused by dirt, which
entered the engine because of improper air
cleaner maintenance, re-assembly, or use of a
non-original air cleaner element or cartridge. (At
recommended intervals, clean and re-oil the
Oil-Foam
 element or the foam pre-cleaner, and
replace the cartridge.) Read Operating &
Maintenance Instructions.
7. Parts damaged by over-speeding, or overheating
caused by grass, debris, or dirt, which plugs or
clogs the cooling fins, or flywheel area, or damage
caused by operating the engine in a confined area
without sufficient ventilation. (Clean fins on the
cylinder, cylinder head and flywheel at
recommended intervals.) Read Operating &
Maintenance Instructions.
8. Engine or equipment parts broken by excessive
vibration caused by a loose engine mounting,
loose cutter blades, unbalanced blades or loose or
unbalanced impellers, improper attachment of
equipment to engine crankshaft, over-speeding or
other abuse in operation.
9. A bent or broken crankshaft, caused by striking a
solid object with the cutter blade of a rotary lawn
mower, or excessive v-belt tightness.
10. Routine tune-up or adjustment of the engine.
11. Engine or engine component failure, i.e.,
combustion chamber, valves, valve seats, valve
guides, or burned starter motor windings, caused
by the use of alternate fuels such as, liquified
petroleum, natural gas, altered gasolines, etc.
