My motor leaks around the point where
the exhaust pipe joins the cylinder and

tCmpts TO repair it. I attempted to
callz the leak glth asbestos packing,
nut was unsuccessful What is the
cause OF leak Of THIS nature, and
how can IL be stopped2-Peter VIII

Visable to install new parts 1t is not
advisable to calk q leak, since by do
ing so you simply aggravate the trou-
bic. The pressure Of the exhaust gases
is such that the Joint must be very
tight Calking may stop the leak for
time only.

If you are familiar with a gas en-
CINE you can very OFTEN discover a /
connecting rod bearing knock or q 4
crank shaft bearing knock by careful Z
sounding with a piece Of steel rod One d
end Of this rod should be placed against
the crank case Just back Of the fly !
wheel at a point as near as possible
to the main bearing. If the other end I
of the rod is placed between the teeth /
and the ears closed with the fingers.

the connecting rod bearings or the {
main bearings are loose Likewise /
this same method applies to the for I
ward part Of the motor BY sounding I
over the motor in this manner IL is I
not difficult to place a knock.
II you suspect a main crank shaft I
bearing OF being loose, would suggest 4
that you endeaVOr TO raise and lower l
the fly wheel by means Of a pinch-bar I
and blocking ANY play IN the main (
bearings at the fly wheel end can be I
detected in this manner If this is Z
not sufficient to note 1T is hardly
sufficient to cause a knock In like I
manner the forward main bearing can
be detected Further than this IL viii 4
be necessary 10 take down the lower
half Of the crank case in order to To-
cate positively the particular bearing
causing the knock Motor knocks are
peculiar and differ as motors differ in
construction. The knock you speak Of
may be caused by a bent cam SHAFT
If so. the method Of sounding afOre-
mentioned should locate it.

The front cylinder OF our motor always
carbOniZeS the exhaust valve. The
valve works freely and the valve spring
is all right. We had the piston out
once and put on new rings, and we
also put in a new valve, but the same
trouble exists After running so miles !
the exhaust valve is carbOnized.-

ceives too much oil This may be due
TO the piston being Improperly fitted to
the cylinder 1t may also bes due to
bad rings. The carbon deposits in ]
dictate imperfect combustion, and this
Is either caused by a poor mixture :
within the cylinder or poor ignition, !
which does not properly burn the mix
tUre. If You are using a fOur-unit 4
plug supplying the spark for this CYL {
inder is not what it should be. Would
suggest that you change the coil units
around to prove this If the compress !
sion Of the forward cylinder is the same Z
at that Of the others, IL is hardly pos
sible that there is anything wrong with
the rings. IT very often happens that

cumulate in the combustion chamber

When my car. which is equipped with I
a - magnetic, is running very slowly
on high IL Jerks violently Have eZ-
amined all cylinders and find that they
are in excellent working condition. No
adjustment OF the carbureter seems to
make any material difference but by
shifting the switch to battery the jerk
ing instantly stops and the car pulls
all right. Is the trouble in the magnetic
and if so how can / remedy tx
The trouble you speak Of IS without
doubt in the magnetic You say that it I
misfires only at slow engine speeds
This would indicate that the circuit Z
breaker needs a finer adjustment and
cleaning. Tt also indicates that the Z
magnets are weak At high speed .suf-
ficient current is generated to properly I
iguite the gases, while at slow engine Z
speed the spark generated is weak BY
readjusting and cleaning the circuit
breaker and also remaE netizing the Z
magnets your trouble viii without Z
doubt be eliminated
