Can you give us some advice concern
ing tho scoring of cylinder walls by
particles of q broken spark plug poree-
lain getting down inside the e~yiinders7
10 il possible for the broken particles
to become graduated by the moving
piston 90 that they act ~ an abrasive
on tho cylinder WALTZ
The chances are very small that q
piece Of porcelain would get between
the piston and cylinder. 1t would have
to be a very small piece. as the clear
ance between piston and cylinder Is
usually around COS inch at the top.
The probability Is that the porcelain
would be blown out with the exhaust.
What 10 tho best way to polish q carr
Paste or wax polishes are used to a
greater extent than the liquids. In
applying them the mistake often Is
made in rubbing the paste directly on
to the body. Much better results will
be obtained If the polish Is placed In a
small cloth sack or in q pocket formed
by a piece Of cloth. Then by rubbing
the sack against the body the polish
will Ooze out through the pores in the
cloth. and in this way the paste will
be applied evenly all owe the body
surface. The polishing cloth which Is
used after the paste has been applied
really gives the body its polish.

There is little advantage to be gain.
ed by disks instead Of, or in addition
to, spokes. Two or three years ago
racing drivers tried covering their
wheels with metal disks to reduce wind
resistance, but found that this affect

When cold weather set in ! put two

there 10 in the radiator?
II there has been no leakage in the
cooling system 1t will be sufficient to
add alcohol because the amount Of wa
ter that has been e%vaporated is neg
ligible, for the reason that alcohol has
a much lower boiling point than wa
ter, and, Of course, there is no danger
Of the glycerin evaporating. But II
some Of the solution has leaked out
and you know the specific gravity Of
the original mixture you may easily de-
termine whether to add alcohol or wa
ter or both by of a hydrometer.
Take the specific gravity of the radia-
tor compound and then add water or
alcohol to bring the gravity to its orig
inal value. In case you do not know
the specific gravity of the original mix
ture you might calculate 1t as follows:
Specific gravity Of mixture-percent-
age Of water by weight plus the per-
centage Of alcohol by weight times .83
plus the percentage Of glycerin by
weight times 1.27.
How can q circulating system be
cleaned with solar
Dissolve about one-half pound OF
soda In Ave gallons Of water and pour
1t into the radiator and cooling sys-
tenn, the solution having been strained
before using. The cooling system also
should be drained before application OF
the solution Then run the motor for

should be drained. Then pour In some
clear water, run the engine again and
drain 1t out. 1t should then be as well
cleaned out as such q solution a

Can you tell mo how to mix . good
polish for my car?
A recommended polish Is mixed as
follows: Mix one pint Of turpentine
with an equal amount Of wood alcO-
hol. Then mix together n quart of
water and one quart Of paraffin oil.
The latter two will not mix readily,
and the best way is to put them In
q gallon bottle and shake vigorously
until the best possible union Is obtain
~. When this is done add the previ-
ously mixed alcohol and turpentine
and shake the whole until thoroughly
mixed. Apply this polish with a soft
flannel cloth and rub the surface dry
with another. The polish Is likely to
separate after standing, and 1t should
be well shaken each time it is used.
How often should the timer bs oiled
in my electric system7
One or two drops Of oil every LOCO
miles Is sufficient for the bearing pin
on the breaker arm.
What 10 the proper width or opening

meters2
The size Of the slot in a ~diagonally
cut eccentric ring does not only vary
with the diameter of the ring, but also
varies with the different manufactur-
ers. Some oniy take out the width Of
the cutter, which will be approximate
ly .015 inches. Others make n prac-
