lime, and once I used a radiator &C.
ment to stop a leak in the pump. Cir
culation appears good, and the radiator
is hot top and bottom. Half a dozen
times have put in washing soda, once
a quart of muriatie acid to remove the
lime and once gasoline to remove any
grease. The timing is correct, valves
good, compression low and the cylin-
ders are worn. The mixture is lean.
What do you diagnose and adviser
From the symptoms you have men,
toned 1t seems that the trouble must
be due to using the radiator cement;
but, not knowing its character or chem
ical composition, it is impossible to say
just what will dissolve 1t.
1t may be that the overheating is due
to faulty fabrication. The oil pump
may be worn so that the oil does not
circulate properly, or possibly the oil
leads are clogged up so that the flow
Of Oil Is greatly hindered. An inspec-
ton Of the pump mechanism will read
lily show whether the fault is there.
and IL it is due to dirty oil passages
they can probably be cleaned by flush
ing the system with kerosene.
1t is possible that the water pump is
worp and therefore does not circulate
the water as rapidly as it should. In
spect the fan belt to see whether 1t Is
tight or not, for looseness at this point
will often cause overheating trouble.
Running with too late spark will
cause oyerheating very quickly, and.
although the magnetic Is properly
timed and you are driving with the
spark lever in the same place as before
your trouble occurred, this may be the
case, because it Is quite possible that
the linkage between the spark lever
and the breaker box ON the magnetic
has slipped little. causing the spark
TO occur later than it should.
Which is the best way of stopping
motor to secure a rich mixture for
starting2
The throttle should be opened wide,
causing the motor to speed up, and then
the ignition cut off. If you have dash
printing arrangement on your car, If
you will operate this on cutting off the
ignition very rich mixture will be
drawn into the cylinders.
Will you kindly advise me "a to the
number of miles the average racing
car goes TO the gallon of gasoline?
The number Of miles per gallon va
ries 80 greatly that any fixed figure
cannot be taken as applicable to all
sets of conditions. The reason for this
Is that ia speedway racing speeds are
so much higher than they are in road
racing, for instance. that the gasoline
consumption for the same cars would
be much different were the cOnsump-
ton measured first on the track and
then on the road. The piston displace-
ment also varies to such an extent that
a fixed figure could not possibly apply
to all sizes Of cars. With these circum-
stances In view 1t Is impossible to give
broad average consumption figure for
all gasoline cars because IL such fig
ure were taken based upon all races 1t
would mean absolutely nothing. In
races where the piston displaCements
are limited to 300 cubic inches the gas
oline consumption is somewhere around
six miles to the gallon.
How often should a storage battery
be cleaned and refilIed with liquid?
A storage battery should be tested
and filed with pure water without fail
once every week in summer and every
two weeks in winter.
Can you tell me how to cleanse out
my radiator? The water here is quite
hard, and hence scales form. What
will remove il? Is it necessary to re-
move the rubber hose when cleaning?
Your radiator can be cleaned by the
use of ordinary washing soda dissolv-
ed in boiling water. To a water pail
full of boiling water add a couple of
double handfuls of washing soda,
forming about a saturated solution.
This is poured into the radiator and
the car operated for short time. pos
sibly three or four minutes. to let the
soda thoroughly reach all parts of the
system. 1t IS followed up by clear
water. which rinses out the soda and
the matter which is loosened by its
cleansing action. If this Is done quite
frequently the radiator will be kept
free OF scale. 1t is not necessary to
remove the rubber hose connections
In doing this, as In fact the motor
must be run In order to thoroughly
reach every part of the circulating sys-
TEN with the soda solution. ...
: Would you please tell me what is used
for covering or coating cork floats to
keep them from getting gasoline or wa
teriossed2 ! believe that there is some
thing better than shellac, which; was
formerly used. The shs!!ae forms in
little blisters or air bubbles over the
cork, and then II allows the gasoline to
get inside, which makes the float too
heavy.
Some of the carburetor companies are
now using secret compound for Gov
ering their cork floats. You can, how.
ever. make a very satisfactory job
with shellac by dipping the foat IN
stead of attempting to paint It on. The
shellac Is thlnned with alcohol so that
