The trouble probably lies between

Motor Department. have a 1913
Mitchell car. Afte- running il about
two months there was a knock in
the motor and II IS still there. If
the spark is advanced half way the
engine knocks very badly. When
the spark is retarded there is no
knock / had carbon taken out Of
the cylinders. and IL seemed a little
better. But II Is very bad at present.
i would be very glad 10 learn
through your paper some remedy
for this knock. S. T.
Evidently tho knock is I'm the
connecting rod or crank shaft bear
ings. The only way 10 find 1t is TO
20 over these parts carefully. If
neglected such a knock may de-
velOp serious consequences and may
even wreck the engine.
Motor Department. have a 1918
ear with a 1z-volt storage battery
When water is put in the filler
openings and the car run, more
water comes out OF the tops than !

of the trouble The starter VIII not

recharged ty the manufacturer
agent i. T.
Il would seem that battery is
overcharging. due to voltage regula-
tor not being properly adjusted. If
electrolyte is up 10 its full strength
and starter does not work properly
the trouble may be in a poor con-
nectlou or in the starter itself.
Motor Experimentation Occasionally
I hear a popping noise at my car
buretor. Is il dangerous? Please
give me cause or causes.
BEGINNER.
Popping back or back firing at
carbureto~ Is exceedingly dangerous
IL the CarburetOr has just been
primed or these is much of a leak.
IL is caused by lean mixture. leaky
inlet valve, or electrical troubles at
times IN distributes. which may
cause an explosion in cylinder when
inlet valve IS open. Look over these
parts carefully as occasionally a car
burns and is totally wrecked from
just this cause.
Motor Department.-If I run my
motor steadily though slowly while
the car is standing. the water in the
radiator will boil and stsam even on
a cool day. This trouble developed
only lately. Can you tell me the
cause OF this1 OWNER.
Perhaps the inner walls of the
rubber hose connections have closed;
thereby stopping the circulation. If
not this, then the water pump is not
working as Il should. The trouble
YOU mention clearly indicates poor
circulation OF the water OF the cool
ing system.
Motor Department:-My Ford diff
ferential is becoming noisy possibly
because 1 have not attended TO II
recently. 1 put oil in the engine
regularly. is the differential oiled
from the engine or must 1t be looked
after separately? A. Il.
The Oiling system on the Ford car
merely takes care OF the engine and
gears. The plug on the dinerential
housing must be removed and more
grease inserted at least once a
month. Use "a medium cup grease
and keep it full. II this does not
stop the noise. perhaps you will find

Motor Department: - Could you
please explain how 90 time a car or
what - meant by timing a car?

Timing a car has no meaning but
the valves may Ae timed and the
ignition may be timed. To time the
valves we disConneCt the timing
gears and set the cam shaft or
shafts so that the exhaust valve in
