iStributor exactly at firing point it is
l&posslble to get continuous spark
Nat the sparkling plug in the electric
Asystem which utilizes the vibrator
#induction COIL but not with the sys-
MEM which has q non-Vibrator coil
Tor a high tension magnetic for fur
finishing the spark at the plugs. The
XNlbrator coil has an arrangement
Nlg%hereby incessant sparkling is pro-
#Nuced at one plug at a time as long
#as the points of the timer or dis
Ntributor are in contact. With the
&non-vibrator coil and the magnetic,
high tension current is generated
TO produce single spark Just when
the timer contacts separate, break
jig the primary circuit. The quick
Ter this circuit is broken the more
sSpowerful spark is produced at the
y Eparkplug.
g8 2.-Valve clearance varies from
two to thirty-five thousandths of
sfan inch, according to the make of
\ the motor. Each manufacturing
concern specifies the correct
amount of clearance necessary for
efficient operation of its motors
and such clearance should be main
tanned at all times to obtain She
most mileage from fuel and power
1 during operation. In many cases
the exhaust valve is made to open
trifle more than the inlet valve,
but in no case should the inlet open
further than the exhaust.
3.--If an automobile is continu-
i
locking device for spare tires an al
lowance of per cent is usually
made in the theft premiums, pro-
viding the lock is always used cor
rectly and that it is kept in eff
cient working condition.
4.-To remove an old valve stem
andreplace it with a new one, first
make a small slit or hoie n distance
from the original place Of the stem,
push the old stem into the tube
and withdraw it through the sec
ond hole that is made. Insert the
new valve through this hole and
draw it up tight in its proper place.
Vulcanize the second opening. In
this way the valve stem opening in
the tube Is not injured or enlarged,
insuring a more air-tight fitting for
the new stem.
because of the fact that the
amotor is operating at greater speed
when on high car speed, the car
will vibrate more when low gears
ARE engaged than it will on high
8gear.
u 6.-According to reports of the
q National Automobile Chamber of
n Commerce in June, more than 6S,-
900 automobiles and motor trucks
We're delivered to dealers from fac
&tories over roads and highways toI
Mat month.
81 Tiff leaks are occurring at the
Beats of valves in motor, the
bparkplugs will have an oil Or
sooty appearance. This indicates
Door combustion, and requires
regrinding of the valves.
81 S.-The kind or weight of lubri-
Eating oil for motor should be
Undetermined by mileage and not
model of the motor. If the motor
LIS new or has an entire new fitting
of bearings, rings or pistons the
lighter grades of oil should be used.
fter three to five thousand miles
8raveling a medium grade is re-
hurried. Extensive use after fifteen
10 eighteen thousand miles calls for
heavy oil.
ia 9.-The first patent on rubber
#fulcanization was secured by
Charles Goodyear in 1874. He dis
lowered the vulcaniz;ng process in
1889. Robert w. Thompson took
but the first pneumatic tire patent
in England in 1S45.
8 10.-Distributor troubles which
will cause poor engine operation
such as knocking or misfirlng are
worn brushes, broken. worn or pit
led points, the presence of grease.
bill or water within or outside of
3he distributor case and wrong
placing of terminal wires leading
to the sparkplugs. Water or oil
even on the outside of the housing
may cause a short circuit and con-
sequent skipping Of the engine,
poor condition of the points of con-
4 tact will do likewise. while mis-
placing of sparkling wires will pro-
duce the wrong firing order in the
engine, resulting in serious knock
! ing or total stopping OF its opera
ton.
