HAVE SYMPATHY FOR CAR
TO GET BEST RESULTS
uinc Pain When He Hears
Engine Missing Badly.
TIRES WILL BE STRAINED
There Are Many Ways in Which
tho Careful and knowing Driver
Can Save His Machine From Tn
necessary Strains.

John Jones and Bill Smith are neigh
bore. They werc caught on the same
rise Of prosperity and purchased the
same make OF car. Neither knows very
much about an automobile, yet Jones
has operated his car six months with
practically no expenses for repairs
while Smith has had his car in the ser
vice station on an average OF once n
week. His troubles have been every
thing from rim Gu; tires and dir, in
the carburetcr to burnt out bearing SIS
and scored cylinders.
Tho difference IS that the one has
sympathy for machinery-and the other
has not.
When an engine misses badly the
only emotion the ordinary driver feels
is that there is a disaGrccable vibration
and that he is not getting as much
power as usual. but the real automobile
lover experiences a sensation OF pain
which can DE compared to that of the
musician who hears masterpiece
ruined by some amateur OF limited
musical ability.
MANY PARTS OF CAN FEEL
EFFECT OF MISSING
Tho fast is that many parts on a
car are strained when missing takes
place and particularly when the miss
ing takes the form of bucking. as il IS
commonly described. This particular
condition arises when the missing oc-
ours at such a time that the engine IS
sometimes propcllinG the car and all err
nately the car is propelling the engine.
NJ this time the strains set UP by the
irregular operation OF the engine are
greatest
The vibration OF n missing engine is
due 10 the fact that 1t slows down con-
sderably when the cylinder fails TO
fire and then speeds up TO normal or
dcrs fire in succession.
The engine, except in go far az Il is
held back by the inertia OF the fly
wheel, Is trying to make its speed fuc-
iuate according TO the power impulses.
When these come IN quick succession
It speeds Up, and when some are
skipped It falls. The car. on tho other
hand. is running At a fairly regular
speed Therefore. when tho engine
speeds up an extra strain is placed on
univcrsals, bevel gears and tires and
many other parts and the same hap
pens when the engine tends 10 drop be-
low normal speed. except the forces
act in the reverse direction.
STRAIN ALL COMES on
ONE TOOTH OF GEAR
Bear in mind that there IS really only
one tooth on the bcvel pin!on which is
fully in mesh with the bcvcl gear at
ono time then assume that powerful
explosion takes place after period
OF missing while this particular tooth
on the bevcl pinion is in contact with
its mate on the bevcl gear. Therefore
It Is plain that large part OF the
blow OF the explosion is transmitted
directly through these two teeth The
wonder ia that they stand up SO we'll
The weight OF the car is so great
that. as previously stated. its speed is
practically constant. The result is that
any rapid fluctuations In engine speed
must hc absorbed by give and take in
that when the engine speeds u7 they
are yanked ono way and then when il
drops they are jcrkcd the other way
This strains and wears both tread and
fabric.
APPLY POWER TO
ACCELERATOR GRADUALLY
The same sort OF strains arc pro-
duccd by uneven operation of the ac-
celerator pedal and the more power the
car has, naturally the greater the
strains are. since the engine is livclicr.
Therefore, II ia desirable TO apply pres
sure TO the accclcrator pedal gently
and when driving over rough roads II
