1
In dusty conditions or when airborne debris is present, clean more often.

Not required unless engine performance problems are noted.
Carburetor and Engine Speed
Never make adjustments to the carburetor or engine speed. The carburetor was set at
the factory to operate efficiently under most conditions. Do not tamper with the governor
spring, linkages, or other parts to change the engine speed. If any adjustments are
required contact a Briggs & Stratton Authorized Service Dealer for service.
NOTICE The equipment manufacturer specifies the maximum speed for the engine
as installed on the equipment. Do not exceed this speed. If you are not sure what the
equipment maximum speed is, or what the engine speed is set to from the factory,
contact a Briggs & Stratton Authorized Service Dealer for assistance. For safe and
proper operation of the equipment, the engine speed should be adjusted only by a
qualified service technician.
Service Spark Plug
See Figure: 9
Check the gap (A, Figure 9) with a wire gauge (B). If necessary, reset the gap. Install
and tighten the spark plug to the recommended torque. For gap setting or torque, see
the Specifications section.
Note: In some areas, local law requires using a resistor spark plug to suppress ignition
signals. If this engine was originally equipped with a resistor spark plug, use the same
type for replacement.
Service Exhaust System
WARNING
Running engines produce heat. Engine parts, especially muffler, become
extremely hot.
Severe thermal burns can occur on contact.
Combustible debris, such as leaves, grass, brush, etc. can catch fire.
• Allow muffler, engine cylinder and fins to cool before touching.
• Remove accumulated debris from muffler area and cylinder area.
• It is a violation of California Public Resource Code, Section 4442, to use or
operate the engine on any forest-covered, brush-covered, or grass-covered land
unless the exhaust system is equipped with a spark arrester, as defined in Section
4442, maintained in effective working order. Other states or federal jurisdictions
may have similar laws. Contact the original equipment manufacturer, retailer, or
dealer to obtain a spark arrester designed for the exhaust system installed on this
engine.
Remove accumulated debris from muffler and cylinder area. Inspect the muffler for
cracks, corrosion, or other damage. Remove the deflector or the spark arrester, if
equipped, and inspect for damage or carbon blockage. If damage is found, install
replacement parts before operating.
WARNING
Replacement parts must be of the same design and installed in the same position
as the original parts. Other parts may not perform as well, may damage the unit, and
may result in injury.

Change Engine Oil
See Figure: 10, 11
Used oil is a hazardous waste product and must be disposed of properly. Do not discard
with household waste. Check with your local authorities, service center, or dealer for
safe disposal/recycling facilities.
Remove Oil
1. With engine off but still warm, disconnect the spark plug wire (D, Figure 10) and
keep it away from the spark plug (E).
2. Remove the dipstick (A, Figure 11).
3. Remove the oil drain plug (F, Figure 11). Drain the oil into an approved container.
Note: Various oil drain plugs (G, Figure 11) are installed in the engine.
4. After the oil has drained, install and tighten the oil drain plug (F, Figure 11).
Add Oil
• Make sure the engine is level.
• Clean the oil fill area of any debris.
• See the Specifications section for oil capacity.
1. Remove the dipstick (A, Figure 11) and wipe with a clean cloth.
2. Slowly pour oil into the engine oil fill (C, Figure 11). Fill to point of overflowing.
3. Install the dipstick (A, Figure 11). Do not turn or tighten.
4. Remove the dipstick and check the oil level. Correct oil level is at the top of the full
indicator (B, Figure 11) on the dipstick.
5. Reinstall and tighten the dipstick (A, Figure 11).
6. Connect the spark plug wire (D, Figure 10) to the spark plug (E).
Change Gear Reduction Oil
See Figure: 12, 13
6:1 Gear Reduction (Figure 12)
If your engine is equipped with a 6:1 gear reduction unit, service as follows:
1. Remove the oil fill plug (A, Figure 12) and the oil level plug (B).
2. Remove the oil drain plug (C, Figure 12) and drain the oil into an appropriate
receptacle.
3. Reinstall and tighten the oil drain plug (C, Figure 12).
4. To refill, slowly pour gear lube (see Specifications section) into the oil fill hole
(D, Figure 12). Continue to pour until the oil runs out of the oil level hole (E).
5. Reinstall and tighten the oil level plug (B, Figure 12).
6. Reinstall and tighten the oil fill plug (A, Figure 12).
Note: The oil fill plug (A, Figure 12) has a vent hole (F) and must be installed on the top
of the gear case cover as shown.
2:1 Gear Reduction (Figure 13)
The 2:1 gear reduction unit (G, Figure 13) does not require an oil change.
Service Air Filter
See Figure: 14, 15, 16
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
• Never start and run the engine with the air cleaner assembly (if equipped) or the
air filter (if equipped) removed.
NOTICE Do not use pressurized air or solvents to clean the filter. Pressurized air
can damage the filter and solvents will dissolve the filter.
See the Maintenance Schedule for service requirements.
Various models use either a foam or a paper filter. Some models may also have an
optional pre-cleaner that can be washed and reused. Compare the illustrations in this
manual with the type installed on your engine and service as follows.
