Maintenance
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.
NOTICE: 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.
• 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 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.

and tighten thespark plug to the recommendedtorque. For gap setting ortorque, 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.
