Rhauld be at the rate Of twenty miles
per hour. We have changed genera

There are three. reasons, which might
be given as causes. Of the meters fail
ing 70 read or read inaccurately. This
may be due to a disarrangement in the
meter itself, in the wiring to the meter
or iii insufficient or no current getting
to the Instrument In testing for the
first you can get an entirely different
source Of current running wires to the
meter and noting If it registers. II It
registers across its scale, then you can
attend to the wiring or to the gen.
orator The latter may need brush
trimming or commutatOr cleaning.
Would an explosion whistle which

Such whistles usually cause the cylin'

In most motors 1t Is not necessary to
close the air valve during the warmer
weather, but in some this 10 necessary
all the time unless the motor 10 crank-
ed for about thirty seconds. 1t may
be that your caFburetor is so adjusted
that an unusually lean mixture Is fed
at low engine speeds. and for this rea-

die valve a little more or decrease the
air supply. - .....r

I have a four cylinder motor, the ia-
milton for which ~ furnished BY . low
tenaion magnetic. The compression in
all four cylinders seems to be good, but
BY opening the pet cocks one at time
the explosion in two Of the cylinders 10
I weaker Than in tha other two. Can you
! tell me what can do TO correct this?
Since the compression in each cylin-
der is good. there remains bat the igni-
ton, The mixture. if right for two
cylinders, ought to be right for the
others, provided the manifold gasGetS
| are intact and do not leak air. The
electrodes are probably slightly dtsah-
ranged or the igniter springs weak.
| Would advise your cleaning all the
electrodes, replacing worn parts where
necessary, also refining in order to
obtain synchronOus ignition OF the
charges. The springs which separate
the electrodes at the breakaway
should be sufficiently strong to cause
an abrupt break The duration Of con
tact of the electrodes should be long
enough to permit the current to rise to
Its maximum and produce heavy
spark at the break.
Can you tell me the cause Of a sharp
metallic 'oiaRk being emitted from the
top Of the steering column on my car
when striking a sharp bump
There Is probably end play In your
steering column, and this can be taken
up by removing the necessary number
OF shims at the base of the steering
gear case. The trouble possibly might
be the worm and worm wheel IL
there is too much play between them
this can be remedIed by taking up the
slack through the turning Of the &C.
centric bushing with which the worm
wheel support is fitted. 81.

There is nothing in moth balls to in
JuFe the motor, for the substance Is
nothing more than o product Of heavy
oils and Is technically called naphtha,
Iene. 1t is apparent there is much
carbon in this substance. and 1t will
increase the carbon deposit. Naph-
