models causes the thermostatic coil spring to release its tension on the choke valve,
permitting it to open gradually. Thus as the engine temperature increases, the choke
valve gradually opens, resulting in a leaner mixture being fed into the engine to meet
operating requirements.
Any service required on the Automatic Choke should be referred to your Authorized
Hudson Dealer.
MANIFOLD HEAT CONTROL VALVE on all models is automatic and requires
no adjustment.
FILTER SCREEN CAP (D) should be removed and the screen cleaned every
2,000 miles.
CARBURETOR AIR CLEANERS
THE OIL WETTED type air cleaner, Fig. 17, is used as standard equipment on all
models. In this type cleaner the wire gauze is oil soaked and as the air passes through it,
foreign particles are removed thereby per-
mitting only clean air to enter the carburetor.
At periods of 2,000 miles, or oftener if
local conditions warrant, the filter unit (C)
should be taken out by removing wing nut
(A) and lifting off cover (B). Clean
off old oil and dirt by dipping it in kerosene.
Blow it dry and re-oil by dipping it in engine
oil,
using the same grade as used in the en-
gine. Permit excess oil to drain off and
reinstall it in the cleaner.
For unusually dusty areas, or when cars
are driven extensively on dusty roads, the
OIL BATH air cleaner, Fig. 18, should be
used. This is available as an option or may
be installed by your Authorized Hudson
Dealer. In this unit dirt is washed out of the air
by the oil spray created as the incoming air
strikes the oil in the sump.
Every 2,000 miles, or oftener if local condi-
tions warrant, the unit should be removed from
the carburetor and cleaned. Filter unit (E)
should be taken out by removing wing nut
(D). If heavily coated, the filter unit should
be dipped in kerosene and blown dry. Re-
move all old oil and clean out sump with kero-
sene. Refill sump with one measured pint
