Oil Recommendations
Engine shipped from Briggs & Stratton without oil.
Before starting engine, fill with oil. Do not over fill.
Use a high quality detergent oil classified For Service
SF, SG, SH, SJ" or higher such as Briggs & Stratton
30W, Part Number 100005 (20 oz.) or 100028 (48 oz.).
Use no special additives with recommended oils.
Do not mix oil with gasoline.
Choose the SAE viscosity grade of oil from this chart
that matches the starting temperature anticipated
before the next oil change.
Note:
Synthetic oil meeting ILSAC
GF 2, API certification mark and API ser
vice 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.
*
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 30 oil, if used below 40° F (4° C), will result
in hard starting and possible engine bore
damage due to inadequate lubrication.
Check oil level. Model Series oil capacity is about:
1.3 ltr or 44 oz. for Models 170000 and 190000.
1.4 ltr or 48 oz. for Model 250000.

Fuel Recommendations
Use clean, fresh, lead free gasoline with a minimum of
77 octane. Leaded gasoline may be used if it is
commercially available and if unleaded is unavailable.
Purchase fuel in quantity that can be used within 30
days. See Storage.
In U.S.A. leaded gasoline may not be used. Some
fuels, called oxygenated or reformulated gasolines, are
gasolines 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.
This engine is certified to operate on gasoline. Exhaust
Emission Control System: EM (Engine Modifications).
Do not use gasoline which contains Methanol. Do not
mix oil with gasoline.
For engine protection, we recommend using Briggs &
Stratton Fuel Stabilizer available from an Authorized
Briggs & Stratton Service Dealer.
Check fuel level.

Starting
(see figs.
Start, store and fuel equipment in level position.
Check oil level.
Open fuel shut off valve, if equipped.
CAUTION: OIL GARD, if equipped, (see 7 fig.
is intended to prevent starting an engine that is low on oil.
OIL GARD may not shut down a running engine.
Engine damage may occur if oil level is not properly
maintained and will void warranty coverage. Always
check oil level before starting engine.
If engine is equipped with OIL GARD, and if engine
runs low on oil, light on engine warns of low oil level. If
light flickers and engine cannot be started, or has
stopped and cannot be restarted, add oil. Fill to point of
overflowing at oil fill cap or to FULL mark on dipstick. Do
not over fill.

operate in FAST position.
Note: If equipment manufacturer has supplied battery,
charge it before trying to start engine, as equipment
manufacturer recommends.
Note: Use short starting cycles (15 secs. per min.) to
prolong starter life. Extended cranking can damage
starter motor.
Before refueling, allow

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.
Start engine and warm up approximately 5 minutes
before adjusting. With engine running, place throttle
control in SLOW position. Rotate carburetor throttle
lever against the idle speed screw and hold it. Turn idle
speed screw to obtain 1750 rpm.
Rotate idle mixture valve full travel clockwise and then
counterclockwise. Finally, position idle mixture valve in
middle of travel. Check idle speed and re adjust to
1750 rpm, if necessary.
Move throttle control to FAST position. Engine should
accelerate smoothly. If it does not, adjust idle mixture
valve counterclockwise 1/8 turn.
