does not have a manual choke or a primer.
Choke System: This features a choke to be used for starting in cool temperatures.
Some models will have a separate choke control while others will have a
combination choke/ throttle control. This type does not have a primer.
To start your engine, follow the instructions for your type of starting system.

Maintenance
NOTICE: If the engine is tipped during maintenance, the fuel tank must be empty and
thesparkplugsidemustbe up. If thefuel tank is not emptyand if theengine is tipped in
any other direction, it may be difficult to start due to oil or gasoline contaminating the air
filter and/or the spark plug.
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 theemissions control devices andsystems
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 of the same design and installed in the same
position as the original parts. Other parts may not performas well, may damage
the unit, and may result in injury.
