needs bit Of your attention. As there
are many types Of carburetors in use,
with various methods of adjustment,
and as the charge for carburetor al.
justment usually is nominal, we are
not going to include this In our plate
Of suggestions. But all carburetors in
use on present day cars are similar In

exhaust manifold. Gasoline needs this
additional heat to properly vaporize II,
but-and this is the important hot
weather hint-it needs far less of this
heat in summer than in winter. Many
car owners go all summer with the
hampers In this heat tube closed and
then wonder why the car loses power
on hills and eats gas. The solution is
obvious. Heat tube hampers are sim
pie to open and close. III you've cooled
off a little by now we would suggest
that YOU raise the hood and see
whether you are driving with the tube
open or closed.

Then II you will accept another
suggestion or two. may We recon-
mend the following:
There are three things which are
known to ruin the finish on any
car. namely, soap, cold and heat.
And the greatest of these-well, II
not the greatest, at least the most
continual--is heat. II you have ever
come near having a sunstroke you
can imagine how the hood of your
car feels when you leave II stand

ly appropriate. Did you ever notice
that after you have put air in the tires
the car seems to ride hard" in spite
of the fact that yo uonly inflated them
to the customary pressure. The rea-
son Is puculiar TO summertime and di-
rectly responsible thereto. There are
authorities who claim tires always
generate a certain amount of heat be-
cause OF their friction with the surface
OF the roadway, but In cold weather
the pavements usually are cold and
damp enough to preclude the POSSIBLE
ity Of expansion of the air In the tubes.
But in summer the expansion 10

tire will increase as much as ten
rounds a short while after the car In

The subject OF tires would not be

to paint the emergency tire with a

with tire cover, summer Is the last
call for dinner. Light, heat, cold,
water and oil all attack rubber and
eventually ruin II, but summer Ia es-
pecially generous with the first two
of it's enemies. There Is no reason why
any motorist should accept such un-
welcome generosity.
fabrication Neglected.
Switching off to another angle az
the subject we venture to say that
fabrication is perhaps one of the most
neglected features of the battle
against hot weather. Grades of oil
and grease that were just exactly
right for winter use are not at all
suited to conditions of the chassis
in summer. A transmission for ex-
ample, that will perform quietly on
even motor oil in winter will re-
quire heavy transmission oil, fiber
grease or graphite to keep II well
fabricated in summer The same
may be said of the differential and
the pinion gear, though grease is
rather too extreme for use in the
rear of the car because the parts here
do not operate at so high a speed as
in the engine and transmission.
In summer one has to choose a
very careful course between two ex-
tremes. Lubricant that is too light
will find way out of it's place of
business. When this happens the car
is said to throw OIL" perhaps at the
brake bands or wherever baskets or
retainers are not sufficiently tight.
