MAINTENANCE
ENGINE AND ENGINE PARTS
We recommend that you see an authorized Briggs & Stratton Service Dealer for all maintenance and service of the engine
and engine parts. Use only genuine Briggs & Stratton parts.
WARNING
WARNING
MUFFLER
Replacement parts for the muffler must be the same
and installed in the same position as the original parts,
otherwise fire can occur.
If muffler is equipped with spark arrestor screen,
remove screen for inspection. Replace screen if
damaged or plugged.
SPARK PLUG
.030" (0.76 mm)
WIRE GAGE
Use only Briggs & Stratton Spark Tester (part
number 19368) to check for spark.
Note: In some areas, local law requires using resistor
spark plug to suppress ignition signals. If this engine was
originally equipped with resistor spark plug, use same
type for replacement.
If you perform any maintenance on the engine, first disconnect the spark plug wire
from the spark plug, and disconnect the battery at the negative terminal (electric
starter engines only) to prevent unintentional sparking. Unintentional sparking can
result in fire or electric shock. Unintentional start-up can result in entanglement,
traumatic amputation or laceration. Use only correct tools.
• Do not strike the flywheel with a hammer or hard object because the flywheel may
later shatter during operation.
• Do not tamper with governor spring, links or other parts to increase engine speed.
