What increase in power can expect
by using ether in gasoline and in what
proportion is II used TO gain the best
Of resuits7
The use of ether In fuel will give a
slight increase in power, due to the
more rapid propagation Of the fame.
One-ha1f pint of ether for each ten
gallons of gasoline is used for this pur-
pose, but 1t is not recommended. as IT
is not economical For getting easier

cial ether and one-half gasoline is car

How will incorrect wiring affect my
motor7
The effect Of incorrect wiring on the
motor depends on how the wires are
misplaced. For instance, II the high
tension cables We're changed around SO
that no one OF them went to the right
plug it would be impossible to run the
motor, although an occasional explo-
sion might be obtained. If two or
three of the high tension wires werc
1nterchanged. but one or more were
left on the correct plugs, then the mo-
tor would run on the cylinders in
which the latter were. Where dual
system is employed the wires of the
battery system may sometimes be mis-
placed without interfering with the OPP
Grafton OF the magnetic and vice versa.
As a rule. however, the changing Of
the wires will result in the whole igni-
ton system becoming imperative.
Has a long stroke motor any advan-
tases over a short stroke motor?
Yes. The gas after ignition has
greater chance to give mp it's energy
to the piston. A greater volume of gas
may be gotten into the cylinder without
increasing the bore. This means more
power for the same piston speed.
How can | take up the end play in a
crank shaft without putting in new
heartngs2
1t is best to replace the bearings
when end play develops, buff this is
not desirable the play can be removed
by moving the thrust bearing to one
side enough to compensate for the
wear. The thrust is taken by the CEN
ter main bearing. which is easily dis
ttnguished by having large flanges on
each side. Remove the bolts holding
the bearing to fine crank case and file
out the bolt holes enough to permit the
bearing to be shifted. Then replace
the bearing and tighten the bolts care
fully.
How will running with retarded spark
make the water boi: in the radiator?
Operating motor with retarded
spark will cause overheating by retard-
ing and prolonsing the combustion of
the charge throughout the power of eS-
pansion stroke. Thus the cylinder
walls are exposed TO the action OF the
burning gases during the whole OF the
stroke instead OF only during the time
the piston is III the region of upper
dead center. as is the case when the
spark is properly set. IL the spark Is
advanced to the point of most efficient
operation the spark will occur some
time before dead center and maximum
pressure Will be reached and the COM
bustion nearly completed just after
dead center has been I..ssed. During
this time. since the piston is near the
face exposed to the exhaust gases IS
minimum, and. furthermore, at this
point in the stroke the compression is
at its height, and combustion takes
place with greatest rapidly. Contrast
these conditions with what happens
when the spark is greatly retarded.
Let US assume that ignition occurs
when the piston has half completed It's
80 20. ton
is lower, and combustion is therefore
slower and viii probably not be com
pleted until after the exhaust valve
opens. The hot gases nre in contact
with nearly the whole OF the cylinder
wall surface for practically one-half
revolution.
But this is not all. When the spark
is retarded. as in the instance just
mentioned, the motor does not develop
full power, therefore for given load
on the motor the throttle must be
opened wider and more gasoline and
air must be supplied. The extra heat
generated by the combustion of the
Increased amount OF fuel thus adds its
share to the already overheated motor.
My car is equipped with electric
lights and would like to know If dry
batteries would work the head and tail
lights. II SO, how many and about /
how many hours would they last?
Dry batteries are not suited for light
ing, the head and tail lights. This
method would be entirely too eSpen-
sive, as the number OF batteries you
would require would be great and their
life short: Take your storage battery
to battery repair man that you are
certain is an expert--if possible take it
to, a service station maintained by the
maker OF your battery-and have it ex-
amined. 1t may be that all it needs is
an overhauling to make 1t as good as
