ANY woman who wants to obtain
fullest cooperation from her repair
man should be keen in observing the
behavior Of the car. Every symptom OF
trouble should be noted, together with
the speeds at which that trouble starts
and stops or Is most pronounced. For
instance, q rouRhness II one OF the new
cars at speeds ~ Jm 23 to 20 miles

repairer will be more apt to know
what's wrong. In the case mentioned
he would simply remove the damper
and clean 1t.
One Of the most ingenious women ]
have met manages to obtain good light
for backing out the driveway At night
even though her car isn't equipped with
a backing light. She closes the doors
of the white garage and switches on the
headlights. The indirect lighting Ii
surprisingly effective.
This is the year 1929, and a number
Of things the men folk did In the old
days are decidedly outmoded. few
Of them are:
Racing the engine when stopping It.
Retarding the spark when crapking
with the self-starter. Alternating be-
tween the foot and hand brake when
going downhill Putting the oldest
! tires on the front.
Women will do we'll to avoid trying to
crank the engine with the cars mo.
mentum on o down grade. Often this
results in straining the engine. gears
and clutch and serves no good purpose.
because cars are driven longer distances
these days and the battery is benefited
by more frequent use OF the starter.

the surest clues Ii occasional sputtering
and generally poor results from under
the hood, because more sediment ana
water is drawn into the carburetor when

bers to drain the gas filter.
Automobile statesmen often stress the
matter of spring design, and 1t is a good
| idea for women to know what It's all
about.
A full elliptic spring. for instance, Is
like two sets of multiple leaf springs
joined together at their ends and with
the inverted arcs facing each other.
Sounds technical, but the springs OF
the usual baby coach are this type. A
semi elliptic spring Is just one multiple
leaf spring, or one-half the full elliptic
kind.
A cantilever spring Is a semi-elliptic
turned upside down and attached to the
car so as to suspend the axle at one
end instead of at the middle. The

of the usual semi-elliptic spring, but
usually Is used in pairs.
When Lafayette and the ladies of his
day went riding, the &C. spring was

Gently one of he leading car makers
used this in o special way for q portion
of the rear suspension Of the car. In
I cidentally the springs of the car are its
real shock absorbers. All these other
things we add are properly known as
resistance devices, since they merely
control the action of the springs within
certain limits.
The weeks prize danger trick in driv-
ing is cutting. the corner for a left turn
just as the signal lights are turning to
stop. This brings the car dangerously
close to any machine that is starting
away from the line on the left side of
| the intersection. The driver who tries
this trick fails to recognize the posi-
bility of the pilot to the left starting
off . little before the signal to 60.
And what is a tappet. anyway? Espe-
cially a mushroom tappet. 1t sounds
like a delicacy at course dinner.
The picture is simply this: The valves
OF a conventional L-head engine have
to be lifted up so as to uncover ports
to let gas In and out of the cylinders at
the right time "A rotating shaft, known
as the cam shaft. carries small lobes or
cams do not raise the end OF the valve
stem directly. A short. adjustable rod
is inserted between each cam and valve
stem. Usually 1t has nat bottom, like
a mushroom.
