extremely dusty areas. Each time air filter ele-
ment maintenance is performed, check the air
inlet to the air filter case for obstructions.
Check the air filter element rubber joint to the
carburetor and manifold fittings for an airtight
seal. Tighten all fittings securely to avoid the
possibility of unfiltered air entering the engine.
