When a carburetor does not afford

be adjusted for the operating condi-

countered, and its shortcomings iunusI

Dossible grace. To do this. II Is neceS-
sarv to make the adjustment when the
machine is on the road and the motor
pulling its load under the Migratory Ell

must be made by some person other
than the driver, and, if possible,
should be performed by one who is
familiar with both. the carburetor ana

In establishing earbureter connect
tions, lead washers only should be
used. as leather or fiber is apt to be
attacked by the gasoline LEAKING
unions and clogged Jets being the re-
suit. Most modern connections are
made with ground joints, which re-
quire no washers at all; If they be
( come deranged il is simple matter 10
render them tight by grinding them IN
with a little crocus powder or emery
flour and oil
1t is astonishing how far the life Of
J the steering gear depends on the SKIN

wheel unnecessarily, bringing severe

needless wear on the 'front.' ures- II
pays to learn to drive skilfully, even

/ lihood.
When il is suspected that leak ex-
/ lists in the ignition wiring the most
/ satisfactory way to locate II is TO ais
| connect the conductors, one at time.
| replacing them with temporary con
| nection made with an ample length OF
| free wire, laid outside the motor
/ parts. Especially where the WIRING Is
/ old. Ii is frequently the case that the
cause Of leakage is a break IN the
| insulation of almost invisible size and
/ possibly remote location. The method
/ Of bridging the conductors enables a
/ faulty wire to be located without as
/ mantling the connections, however,
and therefore it is to be recommendeo-

Don't screw the spark plugs into

! facturer of spark plugs They only
/ want to be tight enough to prevent me E
J leakage of gas. If they are screwed
in too tight it breaks the porcelain and

The oil tanks and reservoirs ordi-
! nariIy fitted in motor cars are pro-
| vided with but very small filler OPEN
! ings. and q great deal of eXasperatlon
is often felt by those who are callea
upon 10 fill them with the heavier
| or more viscous oils. These tanks may
he filled more readily If one has the
| forethought first to heat the can from
which the oil is to be poured, This
/ can be done by setting IL into pan
| or other receptacle of hot water or
! BY applying heat directly to It. An
| increase of few degrees in the tenn
! perature of the oil very materially re-
| duces its viscosity and permits OF
! pouring il rapidly through even the
| smallest of tank openings.
'eThe matter of timing motor prop
erly presents a great many difflcul
ties" said George Emo. a coast expert
| Most everyone is OF the same opinion
that the exhaust should open early
! enough to permit a free escape OF the
stroke Just how early this opening
should occur depends on the piston
| sueed of the motor. and on the shape
and size and duration of the valve

probably the six viii take a little
! closing of the exhaust valve Is OF less

( as possibIe without lea ling any con-
| siderable oVerpreSSure IN the cyllnder
In regard to the inlet valve, the Late

piston mas started to create vacuum
