Each time cleaner element maintenance
is performed, check the air inlet to the
cleaner case for obstructions. Check
the air cleaner joint rubber to the car-
buretor and manifold fittings for an air-
tight seal. Tighten all fittings thoroughly
to avoid the possibility of unfiltered air
entering the engine.
CAUTION:----------
Never operate the engine with the air
cleaner element removed,
This will allow unfiltered air to enter,
causing rapid wear and possible
engine damage, Additionally, opera-
tion without the cleaner element will
affect carburetor jetting with subse-
quent poor performance and possible
engine overheating.
