HEAT IS NECESSARY
FOR AUTO MOTORS
Trouble in Starting Car in
Morning Common in
North.

Perhaps the owner of an otherwise
we'll behaved car will be surprised to
find that his motor has developed an
appreciable miss seemingly overnight
when he starts to take it out on one of
become common throughout the more
northerly states Of our country. If he is
motor wise he will know that the time
has come when he must adjust his car
buretor.
The reasons for this are many and.
after a moments reflection, obvious. The
assistance of a certain amount of heat
is necessary in vaporizing the gasoline.
In some motors this heat is applied by
taking the air from a tube surrounding
the exhaust pipe. while in others a hot
water packet is used for the same pur-
pose. When the temperature of the out
side air drops to a considerable extent
the means provided for heating the air
do not raise the temperature as far as is
required by the carburetor adjustment
that was satisfactory for summer. Ihe
air, being colder, does not evaporate the
gasoline and as d result a miSfire will
develop.
Two Cures Prescribed.
There are two cures for this trouble.
One is the taking of extra precautions
to secure a warm supply OF air. and
the other is to make a change in the
carburetor adjustment. The first is that
generally adopted by the carburetor
makers who provide fittings to be attach
ed to the carpuretor when the cold wealth
er sets in. The second method is the
step that the owners Of oarburetors not
having the ho;-air attachment are COM

simply in supplying greater quantity
of gasoline for given weight of air.
For the more progressive owners who
desire to get away from the change Of
ca: buretor adjustment. which means the
supplying of richer mixture and hence
a drop in the economy of the car. the use
of the dash control has been suggested.
In European practice and on many of the
more expensive American cars this at
tachment has been fitted. although many
have left it off with the idea of reducing
complication.
Printing Is Good
The driver with this attachment is
able to take care of climatic change
without making any delicate needle valve
adjustment. The dash control merely
takes care of the amount of air supplied
and does not interfere with the gasoline
adjustments In the least When the
misfire occurs in cold weather it is
merely necessary to shut off the supply
of air slightly and thereby allow the
motor to draw in a richer charge. After
the motor has been run long enough to
allow it to warm up the amount of air
supplied in proportion to the charge can

With many carburetors. the problem
is merely one OF starting. After the
motor has been running few minlues
there is no trouble whatever. FLOODING
the carburetor and printing are common
means of starting in cold weather, as Is
also the shutting OF the air passage

who know of this method. Another trick
that has been tried with success is the
placing of about II tablespoonful of car

the cover placed OH the tin. Through
