it is all right to drill the holes in the
axle tubes. Some cars have such holes
in the axle tubes, such as Chevrolet,
etc.
Dear Barney Oldfield-I have an
Oakland touring car 1919 model. 1t
has been run d little over 5000 miles.
Within the last 200 it has developed a
loud knock which is noticeable when
driving it about 20 or 30 per hour with
spark fully advanced, but when L
close the spark about half way the
knock seems to stop. 1t also can be
heard when car is standing and motor
idling, but then it is very light. Can
you tell me the trouble and the rem
edy? (2) The ammeter does not go
back to zero when the engine stops.
1t always shows around IS charge"
When the engine picks up it also re-
cords higher charge, but when the en-
CINE stops and | turn on the lights it
does not go to the discharge. a
you tell me whether this would weak
enthe battery and how could L pre-
vent this?-H. /. o.
Perhaps this is nothing more than
a fuel knock, but you must check the
iSiIIIOh LlIIliIs " oEC thni ~ - n.y.
| set too early. / do not believe there
is a loose wrist pin or piston if the
noise goes away under load.
(2) The trouble is in the meter
itself. Perhaps the hand sticks or is
bent. Have a battery service station
try their test meter on your meter
connections and it will tell at once
if your meter needs replacement. 1t
will not weaken the battery if it
shows charge.
Dear Barney Oldfield-Please ad-
wise me how to take out spots from
the inside Of an automobile top, caused
by rain and dampness.-H. Q. ?.
If it is a good mohair lining, use a
good grade soap. If you wish you
may use ether or d good gasoline. APP
ply once we the spots. Do not use
too much Of the cleaner.
Dear Barney Oldfield-Please, cx-
plain to me why shift gears are used.
How and by what principles do they
work?-Y. q. T.
Gears in the transmissions are
used simply to get different lever
age on the rear wheels. The engine
ability must be assisted by means Of
gear reductions SO that the engine can
turn fast and the rear wheels slowly.
This lets the engine develop a lot of
power which it cannot do at low en-
CINE speeds. The gear reductions per
nit of these different engine speed
depending on load conditions.
Dear Barney Oldficld-I have a
1917 Ford touring car and am having
trouble with it misfiring. | have had
this car o~verhauled and it ran all
right for about 500 miles. ] have had
a new block, pistons and ring valves,
timing gears, coil box and coil points,
| c~ommutator, wires and plugs put in.
I had this trouble before it was over
hauled. When going Is miles or over
it runs all right, but under that it will
buck every now and then, summing all
right for about % feet. If you can
give me your opinion | would appre-
ciate it.-R. r.
This seems to me like a clear case
of weak current due to Il weak mag
neto. As the speed increases the mag
neto generates more current and the
plugs fire well.
Dear Barney Oldfield-I have a
Buick 1920 model 40. After a long
rain or washing the car, it seems to
steer much easier than usual. I do
not think it is merely the wet pave
ment. Please inform me Of the eason
for this. Also what gasoline mileage
ought to be expected for a 1920 K-49
five passenger Buick car. Should
there be much difference between city
and country mileage per gallon of
gas?-H. AZ.
The only reason ! can see for this
Is the contraction Of the metal to the
reduced temperature. Regarding the
gasoline mileage. City mileage. owing
to many starts and stops is y miles.
Country steady running, 1913.
