Although the differential of my car is
well fabricated, cannot stop the sing
ing. What can you suggest2-It- Tum-
bell
It is very likely that the piniOn on
the end of the driving shaft is meshed
TOO deeply with the crown or master
gear of the differentiaI. The noise you
speak of can be eliminated by moving
the two gears slightly apart Most cars
are equipped with an adjustment, so
that the differential, as unit, may be
moved from side to side.

Yes. But it is not advisable to change
the timing of the spark in that manner.
The nOtched nut which YOU speak of is
provided for the adjusting of the open
ing Of the interrupter points. If it is
necessary to arrange for the spark to
come later in the cylinder, 1 would ad-
wise that You retard the 3rmature shaft

It is absolutely impossible for a four
cylinder motor to fire 1-4-3-2. on ac-
count of the shape Of the crank shaft
The crank shaft Of the fOur-cyllnder
motors, with the exception Of very
few models, IS designed 10 that the
and pistons travel together and the
. and pistons directly opposite As
and 4 will also travel together, this
makes il impossible for to follow j
in firing order. The two possible fir
ing orders Of a fOur-cylinder motor are
1-2-4-S and 1-3-4-2. and am assuming
that your car has either one Of these
two orders in answering the question,
as follows:
If you are sure that the plugs Of
and cylinders and the cables leading
from the distributor of the magnetic to
the and 8 plugs are in good order,
there is just one possibility left, ana
that is that the and contacts or
segments Of the distributor are con-
nected to ground in some manner so
that the current gets to the ground
there instead of going TO the spark
plug and jumping across the gap.
1t is unlikely that the trouble is in
the breaker box as long as the and
plugs work when attached to the 1 and
wires. However, for the make Of
magnetic you have on your car, 1t is
advisable to have the interrupter points
separated only 1-5Oth of an inch.
Motoring Department The Herald, Is
the timing on my car correct? can
advance the magnetic either One-Quarter
or all the way and not change the speed
of the motor in the least. Z. NJ
It is evident from what YOU say that
the control mechanism between the
