The use of proper grades of lubricants, particularly in cold weather, is helpful in
starting operations.
Start engine as follows:
1. Depress accelerator pedal slowly one-quarter to one-half way and release. This
places the high idle stop in position to prevent stalling during the starting and
warm-up period.
2. Depress clutch pedal fully to floorboard to disengage the clutch to permit the
battery to crank engine at greater speed.
3. Insert key in ignition lock and turn to right.
4. Press starter button.
If the engine does not start after 15 or 20 seconds of cranking, release the starter
button and after a few seconds repeat the starting operation.
Never pump the accelerator pedal before or after starting operations, as this will
result in flooding the engine with raw gasoline. Should this condition he experienced,
the engine can be cleared of the raw gasoline by cranking the engine with the
accelerator depressed fully to the floorboard.
Failure of the engine to start when the above procedure is followed can usually be
traced to improper engine tune-up or, in cold weather, a combination of this and
improper lubricants. The car should then be thoroughly checked by your Hudson
dealer for the source of the difficulty.
Carbon Monoxide Gas
Carbon monoxide, a poisonous gas, is ever present in the exhaust of an internal
combustion engine. Avoid starting or running the engine in a closed garage—always
have the doors wide open.
ENGINE
The Hudson Terraplane Deluxe "L" head-type engine, developing 96 horsepower
with standard cylinder head, and 102 horsepower with super power dome head, and
the Super "L" type engine, developing 101 horsepower with standard cylinder head,
and 107 horsepower with super power dome head, have been designed to provide the
demands of the most critical car buyer from the standpoint of unusual power,
efficiency and economy.
These features are obtained through the use of a chromium alloy cylinder block
giving great strength and wear-resisting qualities, and the use of silicon aluminum
alloy cam ground pistons fitted to .002" clearance. Silchrome steel valves, seating in
efficiently cooled valve seats machined in the cylinder block, provide freedom from
frequent valve grinding and loss of power.
The use of single down-draft carburetor on Series 81, and down-draft duplex
carburetor on Series 82, with patented radial flow intake manifold, provides unusual
economy and performance on hills as well as the straightaway.
