does driving car in second
speed injure the motor IL driven for
any length of time? What rules
should be followed IL such driving Is
necessary.
Driving car in second speed for
any length of time should be avoided
as much as possible. However, on
long hills. In mud or very rough roads
when lower gear ratios are impera-.
tive. the following rules, II applied to
% car in good working condition, will
out injury to the motor. Do not
drive at q greater speed than ten to
fifteen miles per hour. At this speed
do not drive distances OF more than
two miles without period of rest.
giving the motor chance to cool.
II continuous riding for more than
two miles is required, throttle the
engine to q very slow rate Of speed.
Use good oil with the crank case filled
to the proper level and see that the
cooling system in filled with waten
toyerheating, pour In fresh water very
slowly IL possible to obtain or allow
the motor to cool before continuing
the trip. An engine will not catch
fire from driving In low gear.
2.--What IL the cause Of short
circuit in q starting motor?
There are numerous causes OF
short circuits in a starting motor, tho
most common OF which are burned or
broken wires In the armature OF. field
windings, defective insulation OF
those windings or carbon dust from
the brushes collected upon parts and
within the starter cover. The latter
is a frequent cause Of a short. A
current too strong for the starter
will often burn thru the wires in the
windings, taking q short cut instead
OF following the windings and will
eventually ruin the starter, unless il
is protected with fuse.
Sis 1t necessary to signal before
burning to the right. as is uv..~ when
turning to the left7
In turning car to the right al
ways signal before turning as is done
when turning to the left. Traffic laws
in some states require signalling be-
fore turning in either election, but
| It Is matter Of precaution anywhere
to notify those drivers in your rear Of
your intentions whether turning or
stopping.
4.--What Is a remedy for flooded
cylinders resulting in hard starting7
II the cylinders become flooded so
that the ear will not start after a
number Of impulses Of the starting
motor. remove the spark plugs Of OPP
en- the compression cocks at the tops
Of the cylinders and turn over the
engine a number of times. II neces-
sary shut off the gasolene feed line
during this operation. Before replace
ing the spark plugs clean and dry
them. and see that the proper dis
lance between points is carried out
In each plug.
5.-What Is the position Of the
spark when driving about twenty five
miles an hour2
The position Of the spark control
lever when a car is travelling about
twenty five miles per hour varies
with makes Of cars and condition Of
compression. An average is three
quarters open at this speed.
6.-Can distilled water be used at
ter standing a considerable length of
timer
Distilled water, if tightly sealed so
that no foreign substance can enter
it, may be used no matter what
length of time it has been standing.
Z. When going down hill is it adj
visable to switch off the ignition?
II you wish to coast down q hill
and the size OF the hill warrants con-
tinuous coasting, by all means shut
off the ignition switch, engage a
lower gear and disengage the clutch
When the bottom Of the hill has been
reached turn on the switch before
tho car comes to q stop and re-en-
gage the clutch thereby starting the
motor. DO not engage the clutch
when the car is travelling at high
rate of speed as this may result in
serious damage to the entire driv-
ing system.
| 8. What is the trouble with a cal
which will not stand on hill with
gears and clutch engaged, motor
silent and emergency brakes set?
| A car which will not stand on
hill with gears engaged. motor silen,
and clutch engaged has a motor
with very poor compression anc
brakes with lining worn or bands
out of adjustment. The motor should
be inspected for loss Of compression
thru valves, valve caps. piston rings
or spark plugs and compression
