Answers to Last Weeks Questions.
lit is possible for gasoline to
freeze when cooled to 202 degrees
below zero. Denatured alcohol will
freeze at 200 degrees below zero.
2.-The color of the spark de-
ponds upon the intensity of high
tension current passing to the spark
plugs. This in turn is caused by
the winding of Lthe ignition coil
A coil wound for large amperage
but low voltage produces a wide
red spark. A high voltage coil
gives forth a blue-white spark,
while a coil which has part of its
winding short circuited will give
a thin spark, very weak, and one
which will not leap across a wide
gap at the plug points.
3. To stop rafting of Tenders or
braces at bolt fastenings remove
the bolt and insert two steel wash
ers and a soft washer, preferably
of leather, the latter being placed
between the two former, then re-
place the nut. A rafting hood
may he silenced by placing leather
of felt between it and its resting
place
4. The secondary winding of an
ignition coil, consisting of thous-
ands of feet of fine copper wire is
wound around the primary wind
ing, of shorter and heavier wire
These Windings are insulated from
each other by silk thread.
ga lean carburetOr mixture
foo much air and not enough gaso-
line-is caused by poor float valve,
needle valve or air adjustment,
clogged spray nozzle, feed line or
supply cock at tank or a leaking
inlet manifold. A mixture that is
too rich-not enough air and too
much gasoine--may be caused by
a float valve, which is sticking
open, poorly seating, an air valve
which will not open sufficiently due
to too strong spring, needle
valve with too large an opening or n
float loaded with gasoline, which
! will not allow the float valve to
close.
| 6.-An diversified set of tire
chains can be cut down to fit
smaller tire. If fit properly they
will give as good or better service
than the chain intended for the tire.
IF you do not know the
cause of hard engine starting,
whether it is in the fuel or in the
ignition system, good way to To-
cate the cause quickly is to re-
volve the engine with ignition
switch in the off position and the
throttle fully opened. After
number of revolutions switch on the
ignition while the engine is suil
being turned over. If the ignition
is in good condition the engine Will
start with the first revolution after
the switch is closed.
8.-The automobile magnetic gen
crates. an alternating current. II
differs from the generator or
starting motor inasmuch as it IS
wound for high tension work, hay
ing a higher voltage arnattre, put
no commutator as have the latter
two electrical machines. 1t gem
crates only alternating current
, suitable for ignition, because OF the
= fact that the lines of force from
the north to the south pole or me
magnets are cut with each nan
revolution of the armature, thus
reversing the direction of current
flow each half revolution. IhiS Is
called alternating current.
"a simple mixture for cleaning
hoods. tenders, etc, which have
become cloudy with oil and grease
is to use a half and half solution
of wood alcohol and turpentlne'
, Wash off all mud and dust be-
fore applying. Rub but slightly
enough to cover the surface, ana
vine off Immediately with dry
clean cloth.
1O.-The results of worn or
scored cylinders are excessive con-
sumption of oil and gasoline, soot
and carbon deposit on the spark
Mugs. insufficient power delivery
and in some cases a knock or slap
caused by loose fitting ptstons'

1-Hov, does an electric gener-
ator create current at the stdi
without the aid of a storage pat
terry or other means to make llnes
! of force necessary for tho geheratoi
to produce electricity
when your engine Is loSiile
compression and you are not Ger
tain where the leak occurs, now
can you tell if the valves OF III

greatest efficiency is derived from
them? ,,.
4,-Will standing in a closed tank
for a length of time have any pao
effect on the igniting or vaporlZ-
