GASOLINE TANK
The gasoline tank is located at the rear of the car and has a capacity of 16½ gallons
(13¼ Imperial gallons, or 62½ liters).
A filter screen is provided at the bottom of the tank, surrounding the outlet pipe,
to prevent foreign particles from reaching the fuel system.
An electric gauge located at the front of the tank indicates the fuel level on the
gasoline level gauge located on the instrument panel.
A drain plug is provided at the rear left corner of the gasoline tank to permit
draining the tank periodically to remove condensation and foreign particles that
may accumulate in the tank.

Do not attempt to adjust the carburetor alone. Perform all the following operations
in the order given:

Clean spark plugs and adjust gaps to .032".
1.
Clean distributor breaker points and adjust to .020" maximum opening, as
described under "Breaker Points" (page 42).

Check battery and ignition wiring, being sure wires are pressed down in their
sockets and insulation is in good condition and battery terminals clean.
1.
Set ignition timing as described on page 43.
1.
On Series 81, turn carburetor idling screw (D), Figure 39, into its seat and
back out exactly one turn.
On Series 82, turn the two idling screws (E), Figure 40, into their seats and
back out exactly three-quarters of a turn.

When engine has reached normal operating temperature, adjust intake valve
tappet clearance to .006" and exhaust valve tappet clearance to .008".

If the above operations, properly performed, do not give normal engine per-
formance, the car should be taken to your Hudson dealer for mechanical inspection
.
COOLING SYSTEM

The cooling system has been designed to provide proper cooling under all operating
conditions. It is of the pressure pump circulation type. Super models are provided
with a thermostat and by-pass for temperature control. This provides positive
circulation, combined with a short warm-up period.
