/. High-tension current induced in
the secondary circuit of an ignition
coil requires a voltage of about $4,000
volts to cross an air gap Of one-fourth
Of an inch.
2. A common cause of leakage in
lcarburetor which has had consideraoie
usage Is a loaded float. hole in
hollow float SO small that the eye
cannot perceive it. will admit gaso-
line, weighing 1t SO it cannot rise 70
the proner level to close off the adj
mittance of fuel through the lniet
needle valve Another cause Is THIS
inlet valve, the end of which becomes
worn out of round, not seating prop :
erly and allowing a SINAI, now ~
gasoline when the flow should De smut
off entirely. sticking hoal OF 'ai''
will also permit leaking.
3. A good solution to protect ootn
interior and exterior OF ure casiis
is made as follows: To one QUAR- of f
cold patch cement add quar- "
gasoline and about five POUNDS oi
whitening material mixed. oti mse
and keep covered when not IN Ms Ms,
Apply to the tire with brush; ne
above will make a gallon or Solutioh.
4. The differential of full hoatins
axles is removed by Withdrawing 90. Il
axle and shafts. which transmit tIe
drive from the main SHAFT 10 'he as
wheels. and removing in some cases
the cover plate at the rear OF the
housing. 1t may also be withdraw II
from the front of the housing win
the main shaft. The rear Wheels or
housing of axle and differential 90 hot
have to be disturbed.
s. The unit used in meausrlnS tiie
capacitv of storage battery is am :
pere hour. or current to the amour.
of one ampel flowing for the perioo
of an hour. Volume or flow OF cur
rent from a battery is measured IN
amperes To decide the proper SIZE
of battery for the car. decide the
amount of current the battery VIII
have to deliver. Consider the kind OF
Iamps whether carbon or tungsten,
and how many of these VIII be used
at the same time. Total amperage
can be found by adding the totals
of the number and KIM OF lamps;
their voltage and current required
for each Using six-volt tungsten lamps,
two lamps of twelve candle power each
for headlights. two side lights ana
tail light are equal to thirty candie
power or five amperes. At TINS rate
of discharge. six-volt battery Tor
starting and lighting. 14hs inches, by
-. inches and 1O% inches high will de-
Liver current continuously for twenty
eight hours and forty-eight minutes
without being charged.
6. Difficult shifting into a low
speed when the car is at the curb
with engine running would be caused
by the dry plate clutch having worn
fabric on the clutch brake or wrong
adjustment of clutch or brake. To
make easy shifting. renew the brake
fabric, or adjust the brake forward
so that spinning of the released
clutch member will cease when pedal
is depressed Spinning of the main
transmission shaft continues as long
as the released clutch turns.
Z. To determine the correct size
Of gear for the Notwithstanding
style of speedometer. the number OF
teeth in the large gear should be
twice the number of inches in the
diameter Of the tire. If larger tires are
used, change the speedometer gear to
get correct mileage.
S. One cause of humming in the
transmission may be misalignment
Of engine. clutch and transmission.
A strain. and consequently hum.
will result if transmission is not in
straight line with driving shaft or
true with clutch and crankshaft of
the engine.
9. The average valve setting Of over
one hundred makes of cars Is: In
