Tmes-The motor in my motor
cycle has been leaking oil around
the joint Of the base and where the
cylinders bolt on TO the base. Have
had it apart twice and shellsced it,
but does not stop it. How can L
stop it? While running il never
smokes, no matter how much oil il
gets. When running with spark ad-
vanced and throttle closed IL fires
at times with an awful noise. / have
no trouble starting the motor, but
| h2re these troubles when running
Will you tell me how to overcome
them? c. L. II.
After removing motor from frame.
| take cylinder of, and separate
crank case. With a scraper clean
away any old shsilac which may be
coated 10 the surfaces. and then test
with prussian blue for high spots.
/ File until a smooth surface is reach
/ ed. and fit with a gasket made from
/ 1872 in. Asbestoylete. The use of
\ black lead is recommended instead
| of shellac. The after firing you
mention is evidently caused by a
/ faulty carburetor adjustment When
a carburetor is metering out, a faul-
/ " mixture. misiring Of the charge
/ takes place. This unburned gas is
/ forced into the exhaust pipe and
/ muller. The succeeding exhaust
/ quite often will ignite this and
cause the explosion you have noted.

clearance volume in percent of pis-
ton displacement of a four cycle

with the design and size of the en-
gine?.
! The clearance ratio varies wide

know OF anything that will dissolve

stop leak, which has plugged the
radiator. Have tried washing soda

After removing radiator from car

| Tines have a 1917 four-cylinder
Studebaker. There is a groaning in
rear end. When / attempt 10 pick
up speed quickly motor will knock.
also when / engage clutch in sec
Ond and high gear car will jerk and
| jump. What do you advise as the
remedy for these troubles? In what
! condition should L leave car when
stoPed for winter? Should pet
cocks be left open and tires taken
/ off when lacked up. Is it necessary
to be warm in garage? E D. r.
The grooming shows that gears
are not properly meshed. The knock
| is probably due TO carbon Clutch
needs little neatsfoot oil, Drain out
all water and jack up all four
wheels for winter storage Remove
battery to a warm place. but car
does not need to be kept warm. Pet
cocks need not be open. Tires should

Times-Please print the answer TO
this question in your paper. 1 have
a 1917 Ford delivery car and the
| lights on ii are a bother. One light
which is the left one is always dim
and the right one is always bright
and the car is in Al condition. 1t
won't 20 over so, but once in a
while il goes 50 at the most. Thank
ing you in advance. ROBERT.
The cause responsible for one
headlight brighter than the other
may he checked up in this manner.
/ First reverse bulbs TO determine
whether it is a defective filament in
the lamp. If upon reversing the
same lamp is poor, then it is the
lamp. II the same side still shows
weak light il is undoubtedly caus-
/ ed by defective wiring.

stove polish? B. 3. p.
