BY testing the solution with a ny
promoter. When fully charged the SO
luton will show n gravity reading be
tween 1880 and 1900 on the Baume
scale. A battery is said to be dis
charged when its gravity has dropped
to 1.15O or under on this scale.
would like to know what to use to
tske off different kinds of r~enickeling
that I have used on the brass parts of
my car-something that will restore
and not harm the original brass sur
face.
The coat Of nickel which is deposited
over the brass will have to be eaten
Off by acid or else scrapej of mechan-
ically. The acid will have a more even
action and Is recommended by large
brass companies. The acids used are a
mixture of nitric and sulphuric in wen
quantities. After the acid has eaten
through the nickel It will leave the
brass and then the acid Is washed off
and the brass repOlished. To get a
very good job 1t would be better to
have the brass rebuffed.
Is it practicable to charge batteries
with the generator on the car? II so.
how often and how long should the en-
CINE be rum
During the winter the battery should
be charged every two weeks. You can
use the generator on the car for this.
The engine should be run long enough
to cause the battery to show a gravity
Of between 1850 and 1900.
recently disconnected the pump and
magnetic shaft on my car to take up a
little play, and also adjusted the car
bon brushes. am getting a good
spark and at the right time, but when
try to crank the motor it kicks back.
Can you tell mo where the trouble is
likely to be?
The cause Of the trouble Is that the
spark is advanced far enough for ordi-
nary running, but Is too far for crank
ing. The result Is that the spark &C.
ours before the piston has reached up
per dead center, and the explosion In
stead Of forcing the motor ahead
throws 1t back In the reverse direction.
The magnetic should be so arranged
that the spark occurs at full retard on
exact dead center. Magnetos are gen
orally set so that the brake I'm the pri-
mary breaker box occurs at this point.
My radiator was frozen and now
leaks when warm. What can ! dor
Temporary relief will be obtained by
using cOrnmeal, the method of applica-
ton being to drop a handful or more
into the radiator, when the circulation
Of the water will naturally enc to COL
lect the substance around the hole, thus
plugging the leak. There are a num-
Der Of radiator compounds on the mar
ket which may be Of value.
Will you please give me a solution to
my troubles with carbon? find IL
necessary either to burn or scrape out
the carbon from my motor at least
every 400 miles, sometimes less. have
tried all kinds Of oils with various re-
suits, the moro expensive oils giving
the best. Have also tried different sixe
jets In the oarbureter, putting kero.
sene in tho intake every week while
the engine is hot, carrying the oil level
about half full, etc, but to no avail.
The cause Of carbonization In this
motor is probably due to too much oil
being pumped into the cylinders. This
would be due to the gauge on the oil
base not registering correctly and
hence bringing the oil level too high. II
Is suggested that you empty all the oil
out Of the oil base, cleaning 1t thor
oughly with kerosene and then refill
ing with twenty-one pints of engine
oil. II the gauge does not register full
at this point bend 1t until 1t does.
10 there any need Of having the ssdi-
ment washed out Of . storage battery
before Il short circuits. or should Il be
eleensd at regular intervals, oven
though II sesms to b in perfect con-
dition7 !
An ignition battery with rather thick
plates may not need cleaning Of the
sediment trap for n year or per-
haps two. In starting and lighting
batteries the period Is longer, and usu-
ally the plates need replacement when
the sediment trap is filled to any ex-
tent.
What may be the cause Of the brakes
not being effective. and how ma 4 b
remsdisdf
The common cause OF brake slippage
II due to oil on the brake bands. This
oil makes its way from the differential
housing to the brake bands and causes
the brake drum to slip. Poor adjust
ment OF the brake rods will cause poor
performance Take a squirt gun, al
II with Kerosene and empty the o n
tents upon the brake bands. This will
tend to dissolve any grease or oil upon
them.
