overhauled, heats up after running only
fifteen or twenty miles and requires 9
gallon and half of water. Il has been
provided with new timing gears, new
wrist pins and new piston rings with a
clearance Of at least 0.0o4. The muffier
has been placed in several different po-
sitions, and both the oiIine and cooling
systems are in good condition. The car
has lots of power and speed and cranks
easily. After standing short time,
however, the cylinders have to be prim-
ed to start. If the motor ran we'll, but
still the valve timing was a little late,
would that account for it's heating up2
And, If not, can you tell me what would
cause it when il did not do so before
everhaulipg?
1t would seem that the most evident
cause of your overheating is due to
some obstruction in the cooling sys-
TEN. Inasmuch as you have just had
your car overhauled and the trouble
was not evident before the overhaul
ing, it would be indicated that in re-
placing the hose you have permitted
one Of the inner layers of canvas to
obstruct the opening, or it may be
entirely possible that you have put the
pump together incorrectly.
We would also suggest that you clean
out the radiator very carefully, as dur
ing the Oyerhauling period some sedi-
ment may have collected In the lower
cooling passages.
There are many other reasons for
Overheating, probably the most obvi-
Gus being too little oil or oil of a
poor grade. A rich mixture combined
with retarded spark will also give
the trouble you name. A too late open
ing of the exhaust valve, preventing
the release of the explosion, will cause
the motor to overhead, as will driving
too much on low gear. 1t may be pos
sible that in adjusting the bearings
you have made them too tight, causing
a large amount of friction, with its re-
sulting heat.
Will you please explain the multiple
disk type cluteh7
A multiple disk clutch is friction
unit composed Of a number Of disks of
steel, brass, asbestos composition or a
of these. The disks are
one against the other between the mo-
tor and the gear set, and when tension
is applied to them-namely, when they
are pressed together-they first slip.
allowing gradual engagement between
the motor and gear set, and then when
maximum required pressure is applied
they lock together by the surface or
skin friction, and the drive is locked
between the motor and gear set The
tension is gained through a heavy coil
spring controlled by the clutch pedal.
Can you give me a description of the
parts and their relation of the vacuum
feed system?
The vacuum feed system has as It's
function drawing of fuel from a GER
tain level TO a higher level without
need Of applying pressure. Applied to
motorcar, with gasoline tank sus-
pended on the rear of a car, the car
buretor must naturally be at a consid-
erably higher level. The fuel is raised
by means of the vacuum tank. Funda,
mentally the vacuum tank Is a Cylin.
der connected at the top through a
pipe with the intake manifold and
through another pipe to the gasoline
tank. When the motor is turned over
the down stroke Of the pistons ere,
ates suction in the intake manifold
This suction is conducted to the
vacuum tank through the connecting
pipe and from thence through the pipe
to the gasoline tank, thus drawing
fuel, by suction, into the well of the
vacuum tank, where the level is con
trolled by float.
My car 10 equipped with electric
lights, and should like 20 know If dry
batteries would work the head and tail
lights. II so, how many cells should
use, and about how many hours would
they last?
Dry batteries are not suited for light.

sive, as the number of batteries you
would require would be great and their
life short. Take your storage battery
TO battery repairman that you are
certain is an expert; If possible take II
to service station maintained by the
maker Of your battery and have 1t ex'
amined. 1t may be that all it needs is
an overhauling to make it as good as
new. But even if you must buy new
battery 1t is better to do this than try
to use dry ).
How will incorrect wiring affect q
motor?
The effect of incorrect wiring on the
motor depends on how the wires are
misplaced. For instance, If the high
tension cables were changed around SC
that no one of them went to the right
plug 1t would be impossible to run the
motor, although an occasional explo
sion might be obtained. If two or three
of the high tension wires were inter
