Can you tell me the best way to put
coal oil in the cylinders for removing
carbon without removing the spark
pluss7
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. IL you do not want to re-
move these then you will have 10 feed
the coal oil through the air intake OF
the carburetor while the engine Is run

engine Is hot and allowed TO remain in

point magnetic.
The two point magnetic feeds to two
sets Of spark plugs, causing two sparks
to occur In a cylinder at the same
time. This increase IN heat value Of
the spark causes increased flame prop
agation or flame spreading, and hence
better combustion and more power is
obtained.
When a c~srburetor floods, what means
should one take to rid il Of such a con-
dition2
Carburetor flooding usually Is caused
by Il gas logged float. When this con
dition exists the float becomes so heavy
that 1t no longer floats on the gasoline
and thus permits too much OF the liq-
uid to enter the bowl. Dirt under the
float 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 1t
Is called.
Why is it better to turn tho valve al
~ternately when grinding than to turn il
completely around?
1t Is better to osclllate the valve than
to turn 1t around completely for the
reason that In the latter case there is
a chance Of growing the seat with the
grinding compound.
Can a vibrator be converted to a nom
vibrator coil for use with a low tension
magnetic?
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 gained, as the magnetic
already has an interrupter and is de-
signed for use with a nonvibrating
coil.
Why is il advisable to space tho pis-
