Carburetor And Engine Speed Adjustment
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 Center 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 unsure what the
equipment maximum speed is, or what the engine speed is set to from the factory,
contact a Briggs & Stratton Authorized Service Center for assistance. For safe and
proper operation of the equipment, the engine speed should be adjusted only by a
qualified service technician.
How To Check The Spark Plug - 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.
Inspect Muffler And Spark Arrester - Figure 7
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 area and cylinder area. Inspect the muffler (A,
Figure 7) for cracks, corrosion, or other damage. Remove the spark arrester (B), 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.
How To Change The Oil - Figure 9

How To Service The Air Filter - Figure 11
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
Never start or 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.
The air cleaner system uses a pleated filter with an optional pre-cleaner. The pre-cleaner
can be washed and reused.
Flat Air Filter
1. Loosen the fastener (D) that holds the cover (A). See Figure 11.
2. Open the cover and remove the pre-cleaner (C) and the filter (B).
3. To loosen debris, gently tap the filter on a hard surface. If the filter is excessively
dirty, replace with a new filter.
4. Wash the pre-cleaner in liquid detergent and water. Then allow it to thoroughly air
dry. Do not oil the pre-cleaner.
5. Assemble the dry pre-cleaner to the filter with the lip (G) of the pre-cleaner on the
bottom of the filter pleats.
6. Install the filter.
7. Install the cover tabs (E) into the slots (F).
8. Close the cover and secure with the fastener.
How To Change The Gear Reduction Oil - Figure 12
If your engine is equipped with a gear reduction unit, service as follows.
1. Remove the oil fill plug (B) and the oil level plug (C).
2. Remove the oil drain plug (A, Figure 12) and drain the oil into an appropriate
receptacle.
3. Install and tighten the oil drain plug.
4. To refill, slowly pour gear lube into the oil fill hole (see Specifications section).
Continue to pour until the oil runs out of the oil level hole.
5. Install and tighten the oil level plug.
6. Install and tighten the oil fill plug.
Important: The oil fill plug has a vent hole (D) and must be installed on the top of the
gear case cover as shown.
