necessary to spin the motor at the rate

engine pick up, with a few quick turns,
or is it necessary to turn it at a very
high speed when using magnetic
only? Compression is good and every
thing else seems to be in good order.
that you can offer Oh 1 should also
like to know whether the self starter
employing acetylene is safe and reli-
able. Is not there danger of bursting
a cylinder with its use?-W. H. f.
In cranking the motor on magnetic
you should do so with advanced spark.
Presumably you are aware Of this;
and, if so, would say that carburetor
needs adjusting. If the carburetor is
out of adjustment the motor viii nat
urally be hard to start. When every
thing is in good adjustment, a few
quick turns should start the motor
CD The acetylene starter has been
practically displaced by the electric
starter, for many reasons. If properly
controlled. the gas starter is not dan
gerous. The writer does not know of
any specific instances where cylinders
have burst because of an acetylene
slater. There are still a number of
gas starters in use which give salts

Motoring Department. The Herald:
Would any injury result to the rear
axle or other parts of car from using
one S1X5 tire and one 36x415 tire, the
rear axle being a full floating one?
The car in uestion is model IS, six
cylinder-G. W.
While it is not good policy to use
different size tires on the rear wheels,
no great amount of injury would re
suit from temporary use. Theoretical
ly, the differential turns as a unit, eX-
cept under conditions when one wheel
encounters greater resistance than the
other, due to road distractions, turn
ing corners, etc. II each rear wheel
is not equal in diameter, a constant
diffeFential action is set up While
this unit is sufficiently capable of tax
ing care of this. it is not good practice
to force 1t, except in emergency cases.
Under ordinary road conditions, the
differential is Obliged to work great
deal
Motoring Department, The Herald: I
have 40-h. p, and lately 1 have
trouble with my spark. When engine
is running on advanced. spark, it
misses on second and third cylinders,
but on retarded she fires on all four.
Kindly advise me what the trouble
may be.-Harry Corey.
With the magnetic advanced, the
spark created is more intense. It is
possible that defective porcelains in
the spark plug cause the trouble, in
that the current short circuits through
the porcelain instead of jumping the
gap Likewise, the more intense cur
rent would be more apt to jump through
secondary wires leading to these two
cylinders. There may be a partial
short-circuit in these wires leading
from the generator to the plugs. Per-
haps the breaker points of the mag
neto are not adjusted rightly. If these /
points are cleaned and properly ad-
justed, your trouble may be remedied.
Would suggest also that a careful in
spection be made of all the intake
manifold gaskets. There should be no
leak at any one of these joints.
Motoring Department, The Herald: I
have -- 40, and I use -- spark /
plugs Every now and then the third
cylinder misses and as soon as I put /
another plug in the cylinder it stops J
missing. I examined the plug which |
presumably made the engine miss, and |
found the porcelain unbroken.- After !
cleaning the parts, I put the plug to- /
gether and put it back into the third /
cylinder. The car ran all right for /
about 20 miles, when the same cylinder
started missing again. Can you kindly |
explain the trouble or give remedy? |
j. c. D.
It is quite evident that the No.
Others This may be due to a poor set !
of piston rings Too much oil may /
work up into the cylinder and cause /
the fouling of the plug. By removing /
the valve caps, you can easily note /
whether this particular cylinder is (
more foul than the others If you find |
it saturated with oil and carbon and /
the others comparatively free from !
same, then you can reasonably assume /
that new rings are needed. Often /
times the trouble is due either to. the /
plug itself, or to the wire leading to !
the plug. An outside leak in the ig-
milton system would cause that cylin-
der to flood with oil even though the
rings are good. You should first de-
termine whether the ignition is prop
e s,rE ~, de delivered vS to the plug then
test the compression of this cylinder, I
and see if the valves work properly. /
As stated before any one of these |
things may cause a misfire and when
a cylinder misfires it is very apt to
flood with oil. A spark plug is quite
often blamed when 1t is not really the
source of trouble.

4 have a touring car which I have !
been running all season, and I think
the muffler is becoming filled with

Ter before it gets bad enough to cause

The best way to clean the muffler
s to take it off and dissemble, then
clean the parts separately. Unless
his is done the result will not be

Please explain the cause and remedy
or the trouble with a gasoline motor
when the cylinders are flooded and
will not start. Why is it so difficult |
o start an engine after the cylinders /

Know how one can tell when they are !
,verprimed and what is the quickest
way of remedying it-R G.
A great many persons make the
mistake of printing the motor too
much Two rich a mixture will not !
gnite any more readily than a poor
mixture Raw gasoline will not ex-
lode; it simply burns slowly Most /
have a printing lever at
ached. If this lever is pulled once or
vice it is sufficient to fix the mixture I
or starting. When printing the
cylinders direct from the petcocks
cry little gasoline should be inserted. |
'he average petcoek has a cup which
filled is sufficient to prime the
ylinder. If too rich a mixture is
Irawn into the cylinder the petcocks
should be opened and the motor
