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: 8
Check the gap (A, Figure 8) 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: 9, 10
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 9) and
keep it away from the spark plug (E).
8
2. Remove the dipstick (A, Figure 10).
3. Remove the oil drain plug (F, Figure 10). Drain the oil into an approved container.
4. After the oil has drained, install and tighten the oil drain plug (F, Figure 10).
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 10) and wipe with a clean cloth.
2. Slowly pour oil into the engine oil fill (C, Figure 10). Fill to point of overflowing.
3. Install the dipstick (A, Figure 10). 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 10) on the dipstick.
5. Reinstall and tighten the dipstick (A, Figure 10).
6. Connect the spark plug wire (D, Figure 9) to the spark plug (E).
Service Air Filter
See Figure: 11, 12
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.
Some models may 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.
Paper Air Filter
See Figure: 11
1. Loosen the fastener(s) (A, Figure 11).
2. Remove the cover (B, Figure 11) and the filter (C).
3. To loosen debris, gently tap the filter (C, Figure 11) on a hard surface. If the filter is
excessively dirty, replace with a new filter.
4. Install the filter (C, Figure 11).
5. Install the cover (B, Figure 11) and secure with the fastener(s) (A). Make sure the
fastener(s) are tight.
Paper Air Filter
See Figure: 12
1. Loosen the fastener(s) (A, Figure 12).
2. Remove the cover (B, Figure 12).
3. Remove the fastener (E, Figure 12).
4. To prevent debris from falling into the carburetor, carefully remove the pre-cleaner
(D, Figure 12) and the filter (C) from the air filter base (F).
5. To loosen debris, gently tap the filter (C, Figure 12) on a hard surface. If the filter is
excessively dirty, replace with a new filter.
6. Remove the pre-cleaner (D, Figure 12) from the filter (C).
7. Wash the pre-cleaner (D, Figure 12) in liquid detergent and water. Allow the pre-
cleaner to throughly air dry. Do not oil the pre-cleaner.
8. Assemble the dry pre-cleaner (D, Figure 12) to the filter (C).
9. Install the filter (C, Figure 12) and the pre-cleaner (D) to air filter base (F) and onto
