MOTORISTS PROBLEMS
Solved for Readers of
The NeWS-TimeS
By William II. Ste1oart. Jr.

Motor Department: - Could you
tell me through your paper II

four cylinder Buick is large enough

Under carr After going wide open
a little distance the engine begins TO
skip and soon stops entirely. Is this
tank defective or too small? READ
Err.
Undoubtedly the tank IS too small.
You should use a larger vacuum
tank. Sine 113-A r. recommended.
Motor Department: - What is
meant by spark advance and spark
retard7 Does advancing the spark
increase it's volume? I understand
that the amount OF spark depends
on the advance. A. L
Advancing and retarjing do not
effect the volume OF the spark. but
rather the time II takes place IN the
cylinder In relation TO the piston po-
sitior If the spark occurs when
piston Is past dead center Il is then
termed retarded. II before dead cen
ter then 10 Is advanced When
crankinR a motor very slowly on
battery system the spark must be
retarded. otherwise an explosion
may take place In the cylinder be
fore piston has reached top center.
and reverse This reversing is
termed a kick. and IS dangerous.
The amount OF advance TO give the
spark when driving depends upon
the speed OF the motor. II the mo
tor is pulling hard and turning over
slowly then the spark cannot be so
g. - ~ Trrr~ nd
fast then the full advance is advis-
able.
Motor Department: - What is
meant by "clockwise'' and anti
clockwfse" on a magneto7 Can they
be used on the same engine? r NJ.
These terms refer 10 the direction
OF rotation OF the armature seen
from the driving end. This is usu-
ally indicated on the OF cover by
the arrow. The magnetic must be
driven In this direction % have the
segments OF the distributor CORES
pond with the opening OF the cir
cult breaker. II amature IS to be
driven I'm the opposite direction the
parts must be changed accordingly.
Motor Departm ent;-Kindly In

plugs give less trouble and last
longer than those made of porce-
lain. READER.
Consistent with the policy Of this
column. we cannot answer queries
OF preference IN design. However.
il might be said that the porcelain
plug IL more easily broken than a
mica plug, but on the other hand II
Is not so likely 20 become saturated
with the products OF combustion.
Motor OBSERVATION-DISCLOSURES is the
meaning OF a direct drive and an I'm
direct drive and an internal drive
rear2 A s.
Direct drive on a selectve sliding
gcarset IS where tho clutch shaft
and the spine shaE. are locked to-
gether on third speed This drives
directly through the gear-set with
out using countershaft or gears. In
direct drive - when the power is
transmitted through the counter
shaft 20 obtain gear reduction. In
ternal drive gear is used ON rear
wheels OF trucks IL consists Of an
internal gear fastened 20 each wheel
The driving axles. instead OF being
40 the hubs Of the wheels. are pro
vided with pinions which drive the
internal gears.
Motor Department.-Ny trouble
20 solve IS this. When I have the
foot brake working right. the clutch
and brake. being on the same pedal.
and one person sitting in the back
seat 10 works fine. When / get
load in the back seat the foot brake
binds and I have trouble shifting
levers I have had good men work
ing on Il and cannot find the trouble.
/ viii look IN the next issue OF the
paper for what YOU think Is the
trouble READER.
The trouble should be located by
examining the brake mechanism
when the Ger IS loaded. Perhaps
YOU have shortened too much the
brake rod running from pedal back.
Leugthen this rod and make neces-
sary adjustments on the two short
rods further back. This viii also
permit more throw 90 clutch pedal
and effect a better clutch release
action
Motor Department: - Indescend-
ing a long hill should one use both
the foot and emergency brake or
Just the foot brake p. T.
