Why is the distance between the
front wheels of a car greater at the
top than at the bottom2
The reason for this is to make steer
ing easier. The object of tipping the
wheels In this manner is to bring the
point of contact between the wheel and
the ground In a vertical line below the
axis of the steering knuckle. When
the line of the center of the steering
knuckle produced Is coincident with
the contact of the tire and the ground
| there is no tendency for the wheel to
be thrown out of line when an obstruc-
ton Is met on the road. On the other
hand, were this point to be somewhat
| inside of the point of contact of the
wheel and the ground there would be
n tendency for the wheel to be turned
about the steering knuckle whenever
an obstruction was met, with the result
that there would be an interference
with the steering.
What is the difference in connecting
| the battery cells in series or in paral-
lei?
When batteries are connected in Sc
| ries the positive poles of n cell are
connected with the negative of the
next. and so on. When in parallel all
the negatives are connected and all the
positives. Connecting in series gives
the effect of adding the voltages, while
connecting in parallel adds the amper-
age. Thus If six one volt cells were
connected in series the result would be
q six volt current, while n parallel the
voltage would be about one.
Will a self starter operating from a
storage battery of six volts and eighty
amperes work from a dry cell, battery
that is, four dry cells that make six
volts and about twenty-five to thirty
amperes?
No. Dry cells are not intended for
such heavy discharges as the starter
requires. A dry battery would not last
long enough to pay for the trouble,
much less the cost. Storage batteries
are rated in ampere hours, while the
dry battery rating of simply amperes

their rated capacity for an indefinitely
short time. Your storage battery will
give you eighty ampere hours, say ten
amperes for eight hours.
Has a cut-out any material effect on
the power of a car?
With most cars the use of the muller
cut-out increases slightly the power to
be derived from the motor. How much
increase may be obtained depends SO
much upon the condition of the muller
and arrangement of the cut-out that no
exact figures may be given. One should
expect at least 5 or 10 per cent increase
In an old car.
Can you tell me why a two cycle mo-
tor backfires in the carburetor?
The reason that a two cycle motor
gives this trouble is that the intake
and exhaust valves open and close at
the same time, the theory being that
the incoming charge of fresh gas blows
the burnt gas out of the combustion
chamber. However, at certain motor
speeds the combustion of the charge Is
not entirely complete when the intake
valve opens, with the result that the
incoming charge of fresh gas is pre-
maturely ignited and fires back into
the carburetor. Usually a two cycle
motor runs smoothly at one or two
rates of speed, but is prone to back
fire at all other speeds, especially
when the motor is accelerated or re-
tarded.
Can you give me some information
on tire care of tires?
The most important thing is to keep
them pumped up to correct initiation all
the time. Never run in car tracks nor
take bumps at high speed. Avoid run
ming too close to curbs, as you are apt
to snag the tires against the rough
stones. Be careful to avoid sharp stones
in the roadway, and examine the
treads frequently. for cuts and stone
bruises. Remove any stones or other
foreign matter that may work itself
into small cuts in the castings. Such
are dpC To yet ldIlHeT anu ldTlHeF uIl-
der the tread the longer they are al
lowed to remain, and this loosens the
tread disastrously. Never let the car
stand in water if it can be prevented.
and avoid Il garage floor that is COW
cred with grease and oil. If you are
going to store the car or leave it stand
ing in the garage for any length of
time jack up the wheels so hat the car
weight is off the tires. Never run on
a fiat tire. This is likely to chew up
the inner tube and rim cut and other
wise damage the casing.
When prime my motor it gives
about six revolutions and then stalls.
The carburetor is new and the spark
seems to be all right as 1t runs when
| prime it. Before starting open the
needle valve two turns and open throt-
tie about half. What is the matter7
Evidently there is a stoppage some
