DESCRIPTION AND OPERATION
DESCRIPTION
The engine is equipped with a
dry-type carburetor air cleaner as-
sembly and thermostatically con-
trolled carburetor air inlet dust as-
sembly (Fig.
1).
The air cleaner body is mounted
on
a sealing gasket located on the
carburetor air horn. The air cleaner
assembly is retained on the engine
by a stud in the carburetor body and
a wing nut above the filter cover.
The replaceable filter element assem-
bly consists of pleated filter paper
encased in a wire mesh screen, with
integral plastic gaskets located on the
top and bottom of the element. The
gaskets prevent entry of dirt and un-
filtered air into the engine.
The thermostatically controlled air
inlet duct and shroud assembly
is
attached to the air cleaner body with
a wing nut. The shroud is positioned
on the left exhaust manifold. The air
inlet duct control mechanism consists
of a valve plate, thermostat, adjust-
able thermostat rod, two springs and
a
retaining clip.
OPERATION
AIR CLEANER.
The air received from the air duct
passes through a silencing chamber
in the air cleaner body and then
through the filter element. After
leaving the filter element, the air
is deflected down into the carburetor.
Dust particles and other foreign ma-
terials are trapped in the filter ele-
ment as the air rushes through it.
AIR DUCT
The temperature of the air enter-
ing the air cleaner is thermostatically
controlled by the carburetor air duct
assembly (Figs. 1 and 2). Air from
the engine compartment, or heated
air from a shroud around the ex-
haust manifold, is available
1o
the
engine.
