The Power That Works For You.
Look For Relevant Emissions Durability Period and
Air Index Information On Your Engine Emissions Label
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 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.
The Air Index is a calculated number describing the relative level of emissions for a specific engine family. The lower the
Air Index,the cleaner the engine. This information is displayed in graphical form on the emissions label.
After July 1, 2000, Look For Emissions Compliance Period On
Engine Emissions Compliance Label
After July 1, 2000 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, B = 250 hours
and A = 500 hours. For engines of 225 cc or more, Category C = 250 hours, B = 500 hours and A = 1000 hours.
The displacement of Model Series 120000 engine is 206 cc, Model Series 200000 engine is 305 cc, Model Series 210000
engine is 342 cc.

Fire or explosion can cause severe
burns or death.
WHEN ADDING FUEL
•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.
•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.
WHEN STARTING ENGINE
•Make sure spark plug, muffler and fuel cap are in
place.
•Do not crank engine with spark plug removed.
•If fuel spills, wait until it evaporates before starting
engine.
•If engine floods, set choke to OPEN/RUN position,
place throttle in FAST and crank until engine starts.
WHEN OPERATING EQUIPMENT
•Do not tip engine or equipment at angle which causes
gasoline to spill.
•Do not choke carburetor to stop engine.
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 pilot light or other ignition
source because they can ignite gasoline vapors.
WARNING
Starting engine creates sparking.
Sparking can ignite nearby flam-
mable gases.
Explosion and fire could result.
•If there is natural or LP gas leakage in area, do not
start engine.
•Do not use pressurized starting fluids because
vapors are flammable.
WARNING
•Operate equipment with guards in place.
•Keep hands and feet away from rotating parts.
•Tie up long hair and remove jewelry.
•Do not wear loose-fitting clothing, dangling draw-
strings or items that could become caught.
Rotating parts can contact or en-
tangle hands, feet, hair, clothing,
or accessories.
Traumatic amputation or severe
laceration can result.
WARNING
•Allow muffler, engine cylinder and fins to cool before
touching.
•Remove accumulated combustibles from muffler
area and cylinder area.
•Install and maintain in working order a spark arrester
before using equipment on forest-covered, grass-
covered, brush-covered unimproved land. The state
of California requires this (Section 4442 of the
California Public Resources Code). Other states
may have similar laws. Federal laws apply on federal
land.
Running engines produce heat. En-
gine parts, especially muffler, be-
come extremely hot.

ENGINE INFORMATION
TECHNICAL INFORMATION
POWER RATINGS: The power ratings for an individual engine
model are initially developed by starting with SAE (Society of Auto-
motive Engineers) code J1940 (Small Engine Power & Torque
Rating Procedure) (Revision 2002-05). Given both the wide array
of products on which our engines are placed, and the variety of en-
vironmental issues applicable to operating the equipment, it may
be that the engine you have purchased will not develop the rated
horsepower when used in a piece of power equipment (actual “on-
site” power). This difference is due to a variety of factors including,
but not limited to, the following: differences in altitude, tempera-
ture, barometric pressure, humidity, fuel, engine lubrication, maxi-
mum governed engine speed, individual engine to engine variabil-
ity, design of the particular piece of power equipment, the manner
in which the engine is operated, engine run-in to reduce friction
and clean out of combustion chambers, adjustments to the valves
and carburetor, and other factors. The power ratings may also be
adjusted based on comparisons to other similar engines utilized
in similar applications, and will therefore not necessarily match the
values derived using the foregoing codes.

*CAUTION: Air cooled engines run hotter than
automotive engines. The use of non-synthetic
multi-viscosity oils (5W-30, 10W-30, etc.) in
temperatures above 40°F (4°C) will result in higher
than normal oil consumption. When using a
multi-viscosity oil, check oil level more frequently.
SAE Viscosity Grades
Note: Synthetic oil meeting ILSAC GF-2, API
certification mark and API service symbol (shown
at left) with “SJ/CF ENERGY CONSERVING” or
higher, is an acceptable oil at all temperatures.
Use of synthetic oil does not alter required oil
change intervals.

FUEL
TYPE OF FUEL TO USE
♦Use clean, fresh, regular unleaded gasoline with a
minimum of 85 octane. On Model Series 90000 use
fuel with a minimum of 77 octane. Fresh fuel prevents
gum from forming in the fuel system or on essential
carburetor parts. Purchase fuel in quantity that can be
used within 30 days.
♦Do not use gasoline left over from summer. Use winter
grade gasoline which has higher volatility to improve
starting.
♦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 (P/N 5041 or single use pouch).
♦This engine is certified to operate on gasoline. Exhaust
Emission Control System: EM (Engine Modifications).
CAUTION: 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 operat-
ing symptoms occur, use gasoline with a lower
percentage of alcohol or ether.
ADDING FUEL
WARNING
•Fill fuel tank outdoors or in well-ventilated area, away
from sparks, open flames, pilot lights, heat, and other
ignition sources.
•If fuel spills, wait until it evaporates before starting
engine.
•Turn engine OFF and let engine cool at least
2 minutes before removing gas cap.
[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.
