Motoring departments there a rule
to determine the horse power of gas
oline motor from the bore and stroke
of the engine, and IL SO, will you kind
~ give it to me through the paper
W. NJ.
The n. A. C. C. formula is always
used. but it leaves out the length of
stroke as unnecessary. Bore times
bore. times number OF cylinders, divid-
ed by 2.5 gives the horsepower Thus,
a four-inch six-cylinder engine would
be figured as follows: 4x4x6 equals
s6. Divided by 2.5 equals 80 horse
power. The stroke Is left out because
1t is assumed the piston travels at
1000 feet per minute which is about
the average speed.
Motoring Department: I have run IA
car about 10000 miles and about three
weeks ago developed severe pains in
the left leg. As you perhaps know, the
REQ clutch pedal when pressed down
to the limit becomes the service brake.
Do YOU think this has anything to do
with the pains, as it requires consider
liable pressure. Have YOU heard of
any cases like it? H. NJ
The writer has not heard or any
pain is caused by the clutch being 100
hard to operate would suggest that
you have installed additional fittings
Of some sort which will increase the
leverage and require less pressure to

after just having engine overhauled
and radiator flushed out. it still heats
very much in short time. Please give
me remedy and obiigc. A. NJ.
Flushing the radiator and cooling
system does not remove me scale and
slime left there by the water. Take
two pounds of washing soda dissolve
with hot water and pour into radiator
through strainer as it dissolves. When
this is done run the car three to four
hours and then drain cooling system.
Do not allow it TO cool in radiator.
Then fill with fresh water If the en-
CINE has just been overhauled the
pump is probably in good condition.
This will be shown by heat descend
ing in radiator. If bottom is cool While
top is hot the pump has failed.
Motoring Department. / have a Ford
car There is a knock in the motor
which develops slightly as the spark is
advanced, but principally as the throt-
tie is opened. What do you suppose
causes the knock? The connecting rod
bearing being worn or the piston pin
bushings being cut out? Also would
you advise any way to locate the cyl
inder in which this knock occurs?
]. L.
There is no way to determine whetn-
CT the knock is at one end of the con-
meeting rod or the other except by in
spection. In motors several years old
1t may be caused by piston slap" due
to worn pistons and cylinders. The
only remedy for this is to regrind cyl
inders and get larger pistons and rings
1t is difficult to locate the cylin-
der at fault, especially in block mo-
tor, but it is sometimes accomplished
by using long stud rod or piece or
dowelling and touching it to the diff
! ferent cylinders while holding the car
close against the other end. The CYL
inder at fault will give the loudest
noise.
Motoring Department: VIII you
kindly answer through your auto col
umns the following questions:
ta) Would it be possible to remove
the shortest leaf in the rear springs
of my carr The full length of the
springs is feet inches and the
shortest one is Is inches long; seven
leaves to each spring, each 4 inch
thick except the shortest, which is y
Of an inch thick. My car seems to ride
hard except when loaded to capacity
Five passenger). don't know the
weight.
