The relation of the ignition spark gap to good carburetion is important.
On pages 1241, 1299, 1301 remarks on the size of gap to use are
given, and while a wider or maximum gap is desirable after engine
is running, there may he trouble in starting a cold engine if the
gap is too wide. One reason for this is, that when starting motor
is placed in operation, the primary voltage is lowered to about
4 volts (see page 232: "ignition operates under three different
voltages, 4, 6 and 8 volts"), consequently the secondary voltage
delivered to the spark plug is considerably lowered, and at this
time, when engine is cold, when gases are semi-liquid, and when
a hot spark is needed, the weakest is produced.
A spark-plug gap of .030" or .031" (,?2"), is con-sidered
good for slow running, and many repairmen set the gap to .030" or
.031", but on some engines where compression is high and starting
is difficult a gap of about .021" to .025" (which is
an average) would probably he better. While this gap is neither
the best gap for starting, nor for proper running operation, it
is probably better with some ignition systems, whereas on other
systems the .030" or .031" gap is best. The gap recommended
by the manufacturer of the car or of the ignition system produces
the hest results under normal conditions.
A thermostatic spark plug is produced by The Moto - Meter Co. Inc.,
of Long Island City, N.F. When cold, as it would be in starting
the engine, the gap is set .015", but when engine warms up
the thermostatic action of the metal causes the gap to increase
to .0:30".
