WARNING
SPARK PLUG
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 igni-
tion signals. If this engine
was originally equipped with
resistor spark plug, use
same type for replacement.
VALVE CLEARANCE
Check valve clearance yearly. (See Tune-up Specifications
on page 6).

WARNING
If you perform any maintenance on the engine, first disconnect the spark plug wires
from the spark plugs, 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.
