Can you tell mo the best way TO put
coal oil in the cylinders for removing
carbon without removing the spark
| plugs?
The only way you can pour kerosene
into the cylinders is through some open
ing, and the only openings provided in
the ordinary motor besides petcOcks
are those occupied by spark plugs and
valve plugs. II you do not want to re-
move these then you will have to feed
the coal oil through the air intake Of
the carburetor while the engine in run
ming. The coal oil gives best results
If poured into the cylinders when the
engine Is hot and allowed to remain IN
the motor for at least ten hours. About
ne-half tlmblerful should be poured
into each cylinder.
What 10 the advantage Of tho two
point magnetic. .
The two point magnetic feeds to two
sets Of spark plugs, causing two sparks
to occur In cylinder ut the same
time. This increase In heat value Of
the spark causes Increased tiarne prop
agation or fame spreading, aud hence
better combustion and more power liz
obtained.
When q earburster feeds, what means
should one take to rid il Of such . con.
dition2 '...,. =
Carburetor flooding usually Is caused
by u gas logged doat. When this con-
dition exists the float becomes so heavy
that it no longer floats on the gasoline
and thus permits too much Of the liq.
uid to enter the bowl. Dirt under the
doat valve will cause the valve to re.
main open and thus permit gasoline to
flow at all times, filling the bowl and
causing the carburetor TO food. as il
is CALEB.
Why 10 il better to turn the valve al.
ternatsiy when grinding than to turn il
eonplstsly around2,,.
1t is better to oscillate the valve than
to turn 1t around completely for the
reason that In the latter case there il
a chance of growing the seat with the
grinding compound.
Can a vibrator be converted to a non.
vibrator coil for use with a low tension
ma9nsto7
! A vibrator coil could be used as a
nOnVibratOr coil by removing the vi
orator mechanism entirely and taking
the primary and secondary terminals
and attaching them to their proper
places. Another way would be TO
short circuit the vibrator terminals
The coil then virtually becomes one of
the nonvibrator type. This practice is
not recommended. and in connection
with a low tension magnetic It might
result in considerable trouble. There
would be little gaaged, as the magneto
already has on interTupter and is de-
signed for use with nonvibFating
coil .s.-'
Why 10 il advisable to space the pis.
ton ring gaps in sas Engines diagsnally?
1t is advisable because the cscapage
Of gas is hindered more than IL the
rings were cut straight.

If you are sure the motor has what

piston striking against the wall Of the
cylinder. Such q slap can be heard If

is hard to tell from your diagnosis

be a valve slap. Such a slap sounds
very much like the faces OF two pieces
