THE EXPERTS SAY.

! To prevent tires from sticking to
| the rims it is necessary to keep the
rims from rusting. This is most sat
! isfactorily accomplished by the use
of fake graphite, mixed into a creamy
J paste by adding small percentage
of gasoline and applied to the rims
just like ordinary paint. The gaso-
| line evaporates and leaves the graph
| lite, which prevents rusting and
holds the tire bead away from the
rim.
| cylinder jacket can be repaired with
out a great deal of trouble in the
following manner, if the pressure the
part has to Withstand is not too
great: Dissolve some sulphate OF
copper in water, and after cleaning
the edges of the crack well with a
file or sandpaper. paint these edges
with the sulphate solution several
times until there is coat Of copper
on them. The crack can now be filled
with soft solder, which will adhere to
the coppered edges.
A popularity of most all amateur
repairmen is that, although they have
work clothes especially adapted to
receive grease spots and car dirt, they
never JULIET " put oh thSoO oid
habiliments for doing ordinary tink-
ering Because. for some reason. they
never expect to get dirty. Ten min
utes' time to change may save SIS
suit.
But if you do have the misfortune
to get grease or oil spots on your
good clothes. here is a valuable hint
that comes from an old dry cleaner.
1t is most effective where the spots
have not been allowed to stand too
! long. First. sprinkle the spotted
places with talcum powder. rubbing
| it well into the cloth. This done. dust
/ more powder over the spots and put
| the garment aside for several hours.
| This gives the powder time to absorb
! the oil or grease. Later, brush the
| spots with a stiff brush, and nine
| times out of ten the process will
leave the cloth entirely free of the
offending spots.
/, The average motorist wastes gall
| Ions of gasoline every year because
| he allows his carburetor to run on
| too rich mixture.
| BY a little study of his carburetor
he will soon learn how to adjust it to
! cut down on the gas or introduce
more air in the mixture. This not
| only means big saving in gasoline.
but less carbon and a Sweeter-running
| engine.
The average motorist has mis-
taken idea that the gravity of gaso-
f; line is an absolute test and proof of
it's efficiency for motor car use. when
| in fact a lower gravity gasoline will
propel a car more miles per gallon of
gasoline.
The reason for this is easily ex-
planned because the lower gravity gas
requires much more air in the car
buretor for proper combustion. Sci
entific tests have demonstrated that
| there is 20 per cent more mileage in
a 63-degree gravity gasoline than
| there is in a 76-degree gravity.
AS the gravity of motor gasoline
has gotten lower each year, 1t Is well
i to remember that a carburetor now
| one. two or three years old cannot
work as efficiently on the present
| grade of gas-unless 1t gets more air.
| After a car has run two or three
| seasons the muller is probably SO
coated with carbon deposit that a
back pressure which represents power
/, loss is set up.
! The only satisfactory method Of
| cleaning out muller in this condi
| ton is to take it apart and remove
4 the carbon by chipping and rubbing
i it briskly with stiff wire brush of
/ the kind used for cleaning files. Kero-
i sene is a great help in softening the
hardened layers before beginning the
scraping.
