Electronic Fuel Management System
The Electronic Fuel Management System monitors engine temperature, engine speed,
and batteryvoltage toadjust the chokeduring enginestarting andwarm up.There areno
adjustments on the system. If starting or operation problems occur, contact an
Authorized Briggs & Stratton Dealer.
NOTICE: Make sure to follow the steps below or the Electronic Fuel Management
System could be damaged.
Never start the engine if the battery cables are loose.
Turn the key to the off position before disconnecting, removing and/or installing the
battery.
Never use a battery charger to start the engine.
Never disconnect the battery cables while the engine is running.
When connecting the battery cables, first connect the positive (+) cable and then
connect the negative (--) cable to the battery.
When charging the battery, turn the ignition switch to theoff position and disconnect
the negative (--) battery cable from the battery.
Do not spray water directly on the Electronic Control Unit.
Carburetor And Engine Speed Adjustment
Never make adjustments to the carburetor or engine speed. The carburetor was set at
the factory to operate efficiently under most conditions. Do not tamper with the governor
spring, linkages, or other parts to change the engine speed. Ifany adjustments are
required contact a Briggs & Stratton Authorized Service Center for service.
NOTICE: The equipment manufacturer specifies the maximum speed for the engine as
installed on the equipment. Do not exceed this speed. If you are unsure what the
equipment maximum speed is, or what the engine speed is set to from the factory,
contact a Briggs & Stratton Authorized Service Center for assistance. For safe and
proper operation of the equipment, the engine speed should be adjusted only by a
qualified service technician.
How To Replace The Spark Plug - Figure
5
Check the gap (A, Figure 5) with a wire gauge (B). If necessary, reset the gap. Install
and tightenthe sparkplug to the recommendedtorque. For gapsetting ortorque, seethe
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.
Inspect Muffler And Spark Arrester
Running engines produce heat. Engine parts, especially muffler,
become extremely hot.
Severe thermal burns can occur on contact.
Combustible debris, such as leaves, grass, brush, etc. can catch fire.
WARNING
Allow muffler, engine cylinder and fins to cool before touching.
Remove accumulated debris from muff ler area and cylinder area.
It is a violation of California Public Resource Code, Section 4442, to useor
operate the engine onany forest-covered, brush-covered, or grass-covered land
unless the exhaust system is equipped with a spark arrester, as defined in
Section 4442, maintained in effective working order. Other states or federal
jurisdictions may have similar laws. Contact the original equipment
manufacturer, retailer, or dealer to obtain a spark arrester designed for the
exhaust system installed on this engine.
Exhaust system parts are installed by the equipment manufacturer. For specific
maintenance and replacement information, contact the equipment manufacturer.
Remove accumulated debris from muff ler area and cylinder area. Inspect the muffler for
cracks, corrosion, or other damage. Remove thespark arrester, if equipped, andinspect
for damage or carbon blockage. If damage is found, install replacement parts before
operating.
WARNING: 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.
