Maintenance
12 BRIGGSandSTRATTON.COM
Regular maintenance will improve performance and extend
the life of the equipment. Use only original equipment
replacement parts. Other parts may not perform as well,
may damage the unit, and may result in injury. In
addition, use of other parts may void your warranty.
We recommend that you see any Briggs & Stratton
Authorized Dealer for all maintenance and service of the
engine and engine parts.
CAUTION: All the components used to build this engine
must remain in place for proper operation.
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.
Unintentional sparking can result in fire or
electric shock.
Unintentional start-up can result in
entanglement, traumatic amputation, or
laceration.
Fire hazard
WARNING
Before performing adjustments or repairs:
• Disconnect the spark plug wire and keep it
away from the spark plug.
• Use only correct tools.
• Do not tamper with governor spring, links or
other parts to increase engine speed.
• Replacement parts must be the same and
installed in the same position as the original
parts.
• 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 any
Briggs & Stratton Authorized Dealer for service.
CAUTION: 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
Replace the spark plug annually. Check the gap (A,
Figure 11) 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.
