WARNING
Unintentional sparking can result in fire or electric shock.

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.
CAUTION: All the components used to build this engine must remain in place for proper operation.
•Use a
•First attach extension cord to electric starter connector and then into a wall receptacle. If additional extension cord is required, use a
•If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a similarly qualified person in order to avoid a hazard.
CAUTION: This engine was shipped from Briggs & Stratton without oil. Before you start the engine, make sure you add oil according to the instructions in this manual. If you start the engine without oil, it will be damaged beyond repair and will not be covered under warranty.
1.Check the oil level. See the How To Check/Add Oil section.
2.Make sure equipment drive controls, if equipped, are disengaged. See the equipment manual for location and operation of these controls.
3.Turn the fuel
4.Turn on the equipment switch (either a rocker (A) or a key (B) switch). See Figure 5. For location of the switch, see the equipment manual.
5.Turn the choke control (C) to the choke 
position.
Note: Choke is usually unnecessary when restarting a warm engine.
6.Push the primer (D) two times.
Note: Priming is usually unnecessary when restarting a warm engine.
7.Rewind Start: Firmly hold the starter cord handle (E). Pull the starter cord handle slowly until resistance is felt, then pull rapidly.
Note: If the engine does not start after three attempts, go to BRIGGSandSTRATTON.COM or call
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.
8.Electric Start: First connect the extension cord to the power cord receptacle (F, Figure 6) and then into a wall receptacle. If an additional extension cord is required, make sure it is a
WARNING: If the extension cord is damaged, it must be replaced by the manufacturer or its service agent or a similarly qualified person in order to avoid a hazard.
9.Electric Start: Depress the push button (G). After the engine starts, first disconnect the extension cord from the wall receptacle and then from the power cord receptacle (F).
Note: If the engine does not start after three attempts, go to BRIGGSandSTRATTON.COM or call
CAUTION: To extend the life of the starter, use short starting cycles (five seconds maximum). Wait one minute between starting cycles.
10.Allow the engine to warm up for several minutes. Then, slowly move the choke
control to the run 
position.
Emissions Control
Maintenance, replacement, or repair of the emissions control devices and systems may be performed by any
WARNING
Unintentional sparking can result in fire or electric shock.
Unintentional
Fire hazard
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.

How To Stop The Engine - Figure 5
WARNING
Gasoline and its vapors are extremely flammable and explosive. Fire or explosion can cause severe burns or death.
•Do not choke the carburetor to stop engine.
1.Turn off the equipment switch (either a rocker (A) or a key (B) switch). See Figure 5. For location of the switch, see the equipment manual.
2.After the engine stops, turn the fuel
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 - Figure 7
Check the gap (A, Figure 7) 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.
