Emissions Control
Maintenance, replacement, or repair of the emissions control devices and systems
may be performed by any non-road engine repair establishment or individual.
However, to obtain "no charge" emissions control service, the work must be performed
by a factory authorized dealer. See the Emissions Warranty.
WARNING
Unintentional sparking can result in fire or electric shock.
Unintentional start-up can result in entanglement, traumatic
amputation, or laceration.
Fire hazard
Before performing adjustments or repairs:
Disconnect the spark plug wire and keep it away from the spark plug.
•
Disconnect battery at negative terminal (only engines with electric start.)
•
Use only correct tools.
•
Do not tamper with governor spring, links or other parts to increase engine
•
speed.
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.
Do not strike the flywheel with a hammer or hard object because the flywheel
•
may later shatter during operation.
When testing for spark:
Use approved spark plug tester.
•
Do not check for spark with spark plug removed.
•

Carburetor Adjustment
Never make adjustments to the carburetor. The carburetor was set at the factory to
operate efficiently under most conditions. However, if adjustments are required, see a
Briggs & Stratton 3/LC Authorized Dealer for service.
NOTICE: The manufacturer of the equipment on which this engine is installed specifies
the top speed at which the engine will be operated. Do not exceed this speed.
How To Replace The Spark Plug - Figure 6
Check the gap (A, Figure 6) 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
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 for
cracks, corrosion, or other damage. Remove 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.
How To Check Coolant
NOTICE: This is a liquid cooled engine. A 50/50% coolant mixture of phosphate-free
antifreeze and tap water is required for cooling, rust resistance, and lubrication of the
water pump.
WARNING
Severe thermal burns can occur by escaping steam or hot coolant.
DO NOT remove radiator cap or reservoir cap if engine is warm or running.
•
Stop engine and allow it to cool before removing radiator cap or reservoir cap
•
and before changing or adding coolant.
1. Check the coolant level. The coolant level must be between the FULL and LOW, or
ADD, marks on the coolant reservoir. If the coolant level is low, add a 50/50%
coolant mixture of phosphate-free antifreeze and tap water to the reservoir.
2. To remove the reservoir cap after engine is cool, place a thick cloth over the reservoir
cap. Slowly turn the reservoir cap counterclockwise to remove.
3. If the reservoir is dry, add coolant to both the reservoir and to the radiator. See the
equipment manual for location, operation, and maintenance of the coolant reservoir
and of the radiator.
4. To remove the radiator cap after engine is cool, place a thick cloth over the radiator
cap. Slowly turn the radiator cap counterclockwise to the first stop. If pressurized
steam escapes from the cap, stand back to avoid injury. After all pressure is
released, push down and turn the radiator cap counterclockwise to remove.
How To Change The Oil - Figure 2
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 wires (F, Figure 2) and keep
them away from the spark plugs.
2. Remove the oil drain plug (G, Figure 7). Drain the oil into an approved container.
3. After the oil has drained, install and tighten the oil drain plug.
Change The Oil Filter
For replacement intervals, see the Maintenance chart.
1. Drain the oil from the engine. See Remove Oil section.
2. Remove the oil filter (H, Figure 7) and dispose of properly.
3. Before you install the new oil filter, lightly lubricate the oil filter gasket with fresh,
clean oil.
4. Install the oil filter by hand until the gasket contacts the oil filter adapter, then tighten
the oil filter 1/2 to 3/4 turns.
5. Add oil. See Add Oil section.
