wish to make It as light and fast as
possible. Will you kindly give me
some points on this matter?
First decrease the weight Of the vehi-
Gle as much as possible, removing all
unnecessary parts-that Is, non-essen-
tial equipment. Since wind resistance
Is a great factor, 1t becomes evident
that every effort should be made to
stream line the car. A long, tapering
hood, coming almost to a point, as In
some racing cars, Is good. Just enough
space should be left in front to allow
air currents to reach the radiator. 1t
Is considered as important to are for
the rear Of the car as 1t is to look after
the front In this respect. After the
parts have been stream lined as much
as possible the mechanical end should
be considered. If possible, the valve
seats should be increased In size and
new and larger valves obtained. The
size Of the valve seats may be increas-
ed with a counterbore. The life of
the valves may be increased slightly
by using larger cams. Setting the
magnetic ahead will cause the motor to
stop If the throttle is set down too far.
If possible, use Il larger c~arbureter, for
If the intake valves are made larger
more mixture can be accommodated.
The FRACTIONAL loss In the motor is re-
duced somewhat by removing one of
the piston rings, but If the pistons have
but two narrow rings this should not
be done. Lighter pistons help matters
materially. Some use an aluminium al
10y, semisteel or steel, while others
take the old pistons and drill holes In
them. Each piston should weigh the
same as any other piston. Use lighter
connecting rods If possible, but do not
remove metal from the old ones, for
the strength may be impaired. New
rods Of stronger metal and thinner sec
ton, or hollow rods, are better.
One Of the first essentials for a
speedy car is to have a pressure oiling
system, with a hand control on the
dash or other place within easy reach
of the driver. This consists merely
of a hand pump drawing oil from the
tank and forcing it to the crank case.
Ball check valves properly placed can
control the direction of flow. The mo-
tors of nearly all racing cars are equip
ped with magnetos of the double dis
tributer type, so that they feed to two
sets Of spark plugs at the same time.
Is it necessary to oil a lighting gen.
erator7
Every week the ball bearings at the
ends of the armature shaft should be
fabricated with four or five drops Of
oil. There are usually oil holes In the
frame through which the spout Of the
oil can may be directed.
What 10 the best method Of cleaning
leather upholstery?
The best thing to apply to the up
ness and keep 1t from cracking is a
good leather dressing preparation.
There are a number Of good nes on
the market. Water in which there. Is
a little ammonia is also q good leather
cleaner, and after using 1t a soft cloth
should be employed to rub the surface
Of the leather dry.
The generator or my car does not
charge the battery or furnish current
at all. The ammeter always registers
zero, but shows the discharge whom
using the lights. have cleaned the
armature and put in now carbon
brushes. 10 there I'M way Of adjusting
to overcome this trouble?
It Is almost impossible to point to
the exact cause Of your trouble, and
we believe that the tinkering made
matters worse. It would be unwise to
attempt to give you instructions on
making regulator adjustments, etc., for
only an expert on your particular sys-
ten cal do the work so that satisfac-
don will result. Write to the maker
and ask that a field service man exam
inc your installation.
Can you explain why white smoke
flows out Of tho right hand exhaust
pipe and none out Of the left hand pipe
In my eight cylinder carr
This is probably due to the right cyl
inder block getting too much OIL, the
excess Of which makes its way to the
combustion chamber and there is
burned.
While adjusting ono Of the bearings
in my rear wheels had occasion to
take q bearing out and in doing 90 lost
n Of the balls. Will il injure the
bearing to run without tho lost ballf
You should replace the lost ball with
a new one, taking particular care to
obtain the exact size, so that all the
balls Of the bearing will be Of the same
size. If you do not replace the lost
ball the additional strain put upon the
others, due to the lost one, may cause
the cutting of the ball race. When this
starts the life Of the whole bearing is
very short.
