have had the valves ground and II
nulls well in low, but will not pick up
quickly. What Is the trouble?
For the past three months there IL
an unusually strong humming noise as
~ II was the motor. A mechanic says
II is the rear axle, but can hardly
think so. What do you think!
A | believe that poor carDuretor
adjustment. in combination with the
cold. Is the cause of your trouble.
What probably happens when you
start. Is that much of the gasoline con-
denses on the manifold, ana, wnen
YOU open the throttle, this gas due 10
the friction of the fast-moving NIX
ture, Is drawn into the cylinders, max
ing the mixture far too rich. You VIII
probably find that there is certain
sneed at which the engine will run
well Immediately after starting, and
that IL you open the throttle very SLOW.
ly it will speed up all right.
See that your spark-plug points aN
not too far apart. Have them as close
as you can without the engine missing.
If the humming noise comes from
the engine, 1t may be due to the hali-
time gears, the pump or the ran, altho
/ am inclined to believe that the me-
chanic was right, as a noise In the rear
axle will be carried along the propeller
shaft and other metal parts and so
seem to come from the front or the
car. II yours is a touring car you
can check this up by running the car
with the rear floor-board removed.
Your car will then tell you If the noise
comes from the rear.
@. have 1916 (-),
which gives me all kinds of power,
and / get about eighteen miles to the
gallon OF gas, but / must use nearly
n quart and n half of oil per one hum
dred miles, and the engine Is always
choked with carbon.
/ have put in new rings recenuy,
but IL has made no difference as re-
CARDS the amount of oil j have to use.
! was told that by drilling a number OF
small holes between the piston rings
that the oil will be given a chance to
run back and so overcome my Oil
trouble.
Why do you think I must use so
much oil, and will drilling the holes In
the piston help?
A. Possibly the new rings have not
worn in properly as yet, and ] would
suggest that you run the car another
five hundred miles or so before dong
anything. as the rings may wear In
and so the trouble disappear.
You may be using too much oil be-
cause you are filling the oil reservoir
too full. The float of the oil gauge
may be punctured and so too heavy,
In this way register too low.
Drilling the holes will undoubtedly
help. To do this, have a groove. about
a siXty-fourth to thirty second of an
inch deep and perhaps an eighth of an
inch wide cut below the bottom ring
and above the wrist pin, and drill five
Or six small holes in this groove pref
erably pointing slightly downward
from the outside of the piston.
Q. l have siX-volt ()
storage battery, which does not light
the lights well or turn the engine well
when starting. One Of the holes takes
about four times as much water as the
other when fill the battery. The am
meter shows that the battery 10
charged ten amperes when run about
twenty miles. Is this too little? A. T. +.
A. The jar which takes SO much
water is probably cracked. ! would
suggest that you have the battery ex-
amined by your battery men. Ten
amperes is n good charging rate, so
that your generator is working prop
erly, and the. trouble is undoubtedly
due to the battery.
Q. Please tell me If I should use
the same grease in my transmission
and differential now as l did during
the summer? 1 used (---) grade
b transmission grease.
A. The grease you were using Is
liable to prove a little heavy for win
ter use. II there was no tendency for
the grease to work out, l would use
very heavy oil, or n grease which will
flow from the can very freely.
Q. Please tell me how the horse
power of an engine is found? l.. b. s.
A. The s. A. T.. horse power rating,
used by insurance companies and most
states as basis for their rates is, ID
squared times the number of cylinders
all divided by 2.5. In this d is the
bore of the engine. Thus the horse
power of siX-cylinder having a four
inch bore, will be 4X4x6 divided by 2.5,
which equals 3S.4
Q. ] have a 1911(--) car,
model 81, which runs well at high
speed for its age, but will not run
1lowly without stalling. 1t has good
compression. and / recently had the
t-) carburetor station adius
the carburetor for me, but II makes
no difference. What Is the trouble?
The car stalls in traffic and so is very
annoying.
A. The low-tension magnetic on this
car did not hold its magnetism well.
] believe If you will have the magnetic
of 1t remagnetized that your trouble
will be overcome. Switching to bat
terry when in traffic will stop the stall
ling trouble until the magnetic can be
magnetiZed
O. To settle an argument please
tell me II the voltage of O large size
storage battery with three batteries is
more than a small one with three bat
teries? H e. IT
A. The voltage of each cell of n
storage battery is about 2.1 regardless
OF its size The voltage can only be
varied by increasing or decreasing the
number of cells. The size of the cells
only affects the ampere- hours of the
battery, which is about the same as
saying the amount of current which
can be stored up.
q. VIII you please advise how 10
proceed to charge the magnets of n
Fcrd magnetic without removing the
magnets from the machine TO he
placed on a recharging magnet as is
the case in the more common types OF
magnetoes. have been told that this
can be done. We have 220 volt n q
