Oil Recommendations (see fig. ©)
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. 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 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.
*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. (Oil capacity is about 21 oz. or 0.6 liter.) Place engine level and clean around oil fill .
Remove dipstick, wipe with clean cloth, insert and tighten down again. Remove dipstick and check oil level. Oil should be at FULL mark .
OR
Remove oil filler plug . Oil should be full to overflowing .
If oil is required, add slowly.Tighten dipstick or oil filler plug firmly before starting engine.
Fuel Recommendations
Use clean, fresh, lead-free, regular, gasoline with a minimum of 77 octane. Leaded gasoline may be used if it is commercially available and if unleaded is unavail- able. 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.
Before refueling, allow engine to cool 2 minutes.
Clean around fuel fill before removing cap to refuel. Fill tank to approximately 1/2 inch below lowest portion of fill opening to allow for fuel expansion. Be careful not to overfill.
Starting (see figs. ¡¢£)
ALWAYS KEEP HANDS AND FEET
CLEAR OF EQUIPMENT MOVING PARTS.
Do not use a pressurized starting
fluid. Vapors are flammable.
Start, store and fuel equipment in level position. Check oil level.
CAUTION: OIL GARD→, if equipped, (see 10 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.
Before starting (see fig. ¢)
1.Move choke control to CHOKE or START position . Note: If engine does not start, remove air cleaner to check choke. Choke must fully close . If not, see Adjustments.
2.If equipment has separate choke and throttle controls, move throttle control to FAST position .
3.Move stop control to ON position , if equipped.
Rewind starter (see fig. £)
Grasp rope handle and pull slowly until resistance is felt. Then pull cord rapid- ly to overcome compression, prevent kickback and start engine. Repeat if
necessary with choke in RUN position and throttle in FAST. When FAST. When engine starts, operate in FAST position.
Electric starter (see fig. £)
On engines equipped with 12 volt starting systems, turn key to START position or press starter button . Repeat if necessary with throttle control in FAST position. When engine starts, 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.
Stopping (see fig. ¤)
Do not move choke control to CHOKE to stop engine. Backfire or engine damage may occur. Move throttle control to IDLE or SLOW position , if equipped. Then turn key to OFF or move stop control STOP or OFF position .
Adjustments (see fig. ¥)
To prevent acci- dental starting, re- move spark plug wire and ground
it before adjusting, and disconnect battery at negative terminal, if equipped.
Throttle control adjustments
Remove air cleaner (air cleaner base not shown for clarity). Loosen casing clamp screw on carburetor or control plate.
If choke control is remote, push bell crank either way until it just touches washer .
If choke control is manual, move casing and wire in direction of arrow to end of travel.
Move throttle control to FAST position. Tighten casing clamp screw. Replace air cleaner.
Fixed governor control
Governor control has been set to permit top no-load RPM specified by equipment manufacturer. If adjust- ment is required, consult any Briggs & Stratton Authorized Service Dealer.
Check stop switch
Move throttle control to STOP position, if so equipped. Governor control lever on carburetor or control plate must make good contact with stop switch. Check and readjust if necessary.
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.
The carburetor on this engine is low emission. Air/fuel mixture is not adjustable. Only the idle speed screw is adjustable. Governed idle has been set to 1750 at the factory.
To adjust the idle speed, start engine and warm up approximately 5 minutes. Then with engine running, place throttle control in SLOW position. Rotate carbu- retor throttle lever against the throttle stop and hold it while adjusting idle speed screw to obtain 1100 rpm.
