stopped for a wEile. I cannot turn IL /
over when I want 20 start again. (

preciate some suggestions from You. |

When you subject your engine TO
excessive hard work you probably
have overheating trouble as well az
insufficient fabrication. Pistons not
receiving tho proper amount OF
fabrication are very apt 10 seize and
score the cylinder walls After hard
work Il Ia advisable 20 allow the mo-
tor TO run idle for a short time be-
fore shutting down. In this way the
c. i!nders will cool of gradually and
he seiEing be forestalled. When
one discovers that the motor Is lag
ging and suspects that the 4 ouble
lies with insufficient fabrication 90 is.
customary TO keep the motor turn
ing idle with as little gas and as
much spark as possible. By doing
this and feeding tho motor more oil,
the liability OF seizure can be OBJ
Waited. II the pistOns once seize
due 10 lack OF fabrication, it IS a
difficult matter 20 get them free. on
tho other hand IL the cooling sys-
tenn IL working properly, IL may be
possible that the pistons and rings
are dtted too tight in the cylinders

Would appreciate II you could tell
me why my car vibrates so when
picking up only. both in low and
high, though none whatever when
reversing? I have a light runabout
four cylinder Kent system OF igni-
ton with disc clutch. L. w.
Excessive vibration when starting
may often be prevented by opening
the throttle more and gradually en-
gagiag clutch. II you have tried
this without effect, perhaps the
clutch takes hold too suddenly, due
probably TO the oil IN which Il runs
being too thin. Try a slightly
heavier grade or mix a little heavy
oil with II. Vibration when picking
up on high gear Is usually caused
by car travelling too slow when
changing gears. A clutch would have
10 be in very bad condition to cause
vibration when reversing. as that
gear is very low.
Motor Department. News-Times:
IF I have four dry cells Of 10 am
peres each connected in series what
is the amperage Of the whole? Does
a poor one cut down the rest?
p. L
The amperage IS that OF one cell
or 10 amperes, but the voltage Is
approximately six. or the sum Of the
voltage OF the four cells when con-
nected in series. A defective cell
when connected in series with good
cells cuts down the efficiency OF the
othsrs and should be removed. In
testing tho cells test each separate
for amperage. not voltage. A new
cell should show 20 or 25 amperes.
The voltage remains practically con-
low. and therefore Is no true test as
to efficiency.
Motor Department News Times:
In looking over several makes of
cars, with "a view, possibly, OF pur-
chasing, a certain salesman laid en-
phRsis on the fact that his car was
equipped with roller bearings. He
laid particular emphasis on this
point and since a number OF other
cars selling at higher prices are not
equipped with these roller bearings
i am curious TO know where the ad-
vantage lies. Would like very much
10 have you answer this In the next
issue OF your column. W S
Opinions OF mechanical engineers
differ as 10 which type OF bearing is
best for use in the automobile. The
type bearing used, together with its
proper design for the work Il has
20 dc. determines its efficiency. Many
high grade cars use annular type
bearings. Still others use both types
in various parts OF the car where in
their opinions. the particular type
serves best. The merit OF the bear
ing used Is determined by its design,
construction and proper installation.
Motor Department. News-Times:
While adjusting one OF the bear
ings IN one OF the rear wheels I had
occasion 20 take a bearing out and
in doing so lost one OF the balls. VIII
II injure the bearing TO run without
the last ball? A G..
You should replace the lost ball
without delay. taking particular
care 10 obtain the exact size, so that
all the balls OF the bearing will be
the same. II you do not replace
the lost bali the additional strain
put upon the others may cause the
cutting OF the ball race When this
starts the life OF the whole bearing

II noticed small leak in one OF
the cylinders this morning which
was caused by a blowhole in the
casting. The cooling water L know
