5. Move the choke control (C) to the choke
Note: Choke is usually unnecessary when restarting a warm engine.
6. Rewind Start: Firmly hold the starter cord handle (D). Pull the starter cord handle
slowly until resistance is felt, then pull rapidly (Figure 4).
Note: If the engine does not start after repeated attempts, go to
VanguardEngines.com or call 1-800-999-9333 (in USA).
WARNING:
Rapid retraction of the starter cord (kickback) will pull your
hand and arm toward the engine faster than you can let go. Broken bones, fractures,
bruises or sprains could result. When starting engine, pull the starter cord slowly until
resistance is felt and then pull rapidly to avoid kickback.
7. Electric Start: Turn the electric start switch to the on/start position.
Note: If the engine does not start after repeated attempts, go to
VanguardEngines.com or call 1-800-999-9333 (in USA).
Maintenance
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.
WARNING:
When performing maintenance that requires the unit to be
tipped, the fuel tank must be empty or fuel can leak out and result in a fire or
explosion.
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.

NOTICE: To extend the life of the starter, use short starting cycles (five seconds
maximum). Wait one minute between starting cycles.

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.
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 Check The Spark Plug - Figure 5
Check the gap (A, Figure 5) 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.
