Refer to the Maintenance Schedule at the end of this section
and ensure that the recommendations are followed. More
frequent service is required when operating in adverse con-
ditions.
Use only Briggs & Stratton spark tester (1) to check for a
spark as shown in the diagram.
Replace the spark plug every 100 hours or every season,
which ever occurs first. A spark plug wrench is available
from any authorised Briggs & Stratton service dealer.
The spark plug gap (2) should be checked with a feeler
gauge and set at 0.76mm (0.030”).

SPARK PLUG SERVICE
- Gain access to the pre-cleaner (4) and cartridge (3)
by loosening screw (1) and tilting cover (2).
- To service the pre-cleaner, carefully remove and
wash in a solution of liquid detergent and water.
Allow to air dry thoroughly before replacing.
- Clean the cartridge by tapping gently on a flat sur-
face. If very dirty, replace or wash in a solution of
non-foaming detergent and warm water. Rinse thor-
oughly with running water from the mesh side until
the water is clear. Allow the cartridge to stand and air
dry thoroughly before replacing. Do not use petrole-
um solvents during cleaning as this will cause the car-
tridge to deteriorate. Do not use pressurised air as this
may damage the cartridge. Do not oil the cartridge.
- After servicing, install the pre-cleaner and cartridge
in the cover. Insert the tabs on the bottom of the cover
into the slots in the bottom of the base (5). Tilt the
cover upwards and securely tighten the screw to the
base.
