VIII you kindly publish the ingre-
the most practicable anti-freezing so
luton for automobile radiator and
Water-cOOled gas engine Thanking
you, I AMI B. Scott.
The most practical anti-freezing So
luton is made up of wood alcohol and
water. A mixture of One-Quarter al
cOhOl and three-Quarters water IS suf-
ficient to prevent freezing at zero tenn
perature. If the temperature falls
much below zero II is advisable to in
CREASE slightly the amount of alcohol

What should be the condition of the
compression chamber in a motor when
working to best adantage2 Should
the piston head and compression space
be dry and sooty, or IN an oily condi-
The condition of the combustion
chamber should be dry and clean. An
oily condition indicates too much oil
and imperfect combustion. The cylin-
der will necessarily be sooty on ac-
count of the products Of combustion.
While there should be no carbon resi-
due. nevertheless it is impossible to
realize such ideal conditions.

7 have noticed on my motor that there
is air pressure coming from the vent
pipe when the motor Is running. My
friends tell me that this indicates a
scored cylinder The motor runs per-
fectly. Would be obliged to you il you
could enlighten me on this subject
S. NJ p.
Vent pipes are installed in the crank
case TO relieve any compression IN the
case. AS the pistons travel up and
down there IS more or less compress
sion. If the cylinder was scored IN the
manner your friend states, the compress
sion on this particular cylinder would
be very weak You state that the mo-
tor runs perfectly, therefore, there ap-
pears to be no cause for alarm,

Kindly state which is preferable, a
leather faced cone clutch or a multi
pie disc clutch running in oil?
Is a light car better equipped with
high tension magnetic only, or with
the dual system Frank CanGelO
You viii find that there are many
high grade cars using the leather faced
cong clutch. There are also many
high grade cars using the multiple disc
clutch running in oil. Engineers differ
as to which is the better. When both
are designed and constructed properly
they are very efficient
The dual ignition system is to be
preferred. Especially will this be
found true in starting the motor during
cold weather.

IN taxing me waves OUT OF my iuOlDL
I noticed that the exhaust valves par
ticularly are very much spotted. One
valve is slightly warped VIII you
kindly advise whether IT is necessary
to get all new valves, or whether it
is necessary to get one new valve Only2
Reader.
You have allowed the valves to go
too long without grinding, hence the
pitting Of the valve seats 1t viii be
necessary to grind these until the
pits or spots disappear and clean,
smooth seat is obtained. As to the
warped valve stem, it is best to replace
this. In replacing it viii be necessary
TO grind in order to obtain a proper
seating Of the valve The exhaust
valves especially should be ground fire.
quently In order to obtain the best
results from motor it is advisable TO
reseat all the valves about every 1000
OF 5000 miles. If this is done there is
less work and much better results are
obtained
