otherwise poor working motor almost

repairing and starting up balky en-
gines that there are just four things
absolutely necessary to the correct
workings of the automobile gasoline
engine and I viii give them here;
First. gasoline in the cylinders un-

Your suggestion as TO using gasoline
brings up an interesting point Il is
slightly preferable 10 mix the graphite
with gasoline, because after the paste

seems TO be that you allow this bolt
to come loose. or when YOU put in
new one YOU do not tighten il suffi-
GENTLY Use a lock washer 10 hold
the nut from turning and in addition
see that the spring clips are kept tight,
because if these work loose an 2ddi-
tionaI strain is placed on the center
bolt. In replacing this bolt. make sure
that YOU obtain one from the Ford
company. Do not use any bolt that
happens to be the right size, as II
may not have the requisite strength

viii give a voltage nearly four times
as great. and this viii cause a tenn
porary current flow nearly four times
as large as with one coil This is
assuming that the WiudinES Of the coils
viii stand this increased voltage. They
may stand il for a short time before
breaking down, but they are almost
certain TO break down in time and they
may give out the moment the current
is turned on.
Do not attempt to improve the isni- ,
ton Of your car in this manner II it
does not work properly. find out what
is the trouble and fix it. II you will
describe your trouble we viii help you.
However, II YOU wish TO use the four
coils in series, merely as an expert
ment, do not do so unless you are will
ing to risk running all four coils
. Under these conditions the cur
rent in the primary would be slightly
less. due TO the fact that the resistance
OF the primary circuit is now four
times as great as it was previously.
Nevertheless roughly speaking. the
current flowing through the primary
may be said TO be about the same
amount whether the primary consists
Of one coil or four coils. because the
resistance in any case is very small

receiving far too much oil There IS a .
valve controlling this supply right back /
Of the oil gage and this should be
opened only about lie Of turn or
just enough to insure a small amount f.
Of oil flowing to the yoke.
Another possibility is that the oil Is
leaking out Of the rear main bearing.
This may be stopped by removing the
lower half OF the bearing and cutting
a trough in the center. the trough slop-
ing so that excess oil will flok back
into the crank case.
In addition make sure that no excess
OF oil finds its way up into the com
hustion chambers, due to loose fitting
pistons, etc
am told that there is no method for .
removing carbon from gasoline en-
Eines which is superior to the use Of
denatured alcohol
Kindly give me a little advice Would I
you apply while engine is hot or cold? ]
How much to each cylinder How long /
shoulG it remain in cylinders
A. y TerrilL
BY al means apply the alcohol
when the motor is hot for the reason Z
that the action of the alcohol is merely /
to dissolve the gummed oil which binds
the particles Of carbon together into a I
hard. solid mass. and when the alcohoI
Is hot IL dissolves the oil more readily. ]
The cylinder should be filled with
alcohol so that it will come into con-
tact with every part of the carbon. 1t
Is best to do one cylinder at a time J
Bring the piston to top dead center on /

are then closed Fill the cylinder with
alcohol and allow il to stand until the

then again il may be necessary to
allow it TO stand over night, or possibly
