wood.
Powdered graphite is not to be rec
commended in the crank case in a |
splash system engine. While graphite
will not materially injure the working !
parts, it will have a tendency to clog |
up the various holes and grooves. and
possibly prevent the proper flow OF
oil to the respective bearing surfaces.
1t Is not necessary, and the advant-
ages to be gained by it's use are not
worth the experiment. Would advise
your using a high grade oil free from
as much graphite or carbon ingre-
dents as possible.

developed peculiar missing. The car

strong spark. The wires are in
good shape also the plugs. What is
the remedy for this trouble?-W. r.
Turner.
The trouble, 1t appears, lies In the
primary interrupter in the magnetic.
one of the cams which operates this
without doubt is worn or defective
and does not cause the interrupter
points to open.
! There are two cams operating the
/ interrupter which works alternatively.
! The firing order of your engine is
either 1-2-4-3 or l-3-4-2, and it is evil
dent that one cam operates for the
spark in l and cylinders and the
other cam for the . and 8 cylinders.
The trouble may be located by re-
moving the magnetic and revolving
the armature slowly by hand. Watch
the interrupter points to see il they
separate properly every half revolu-
ton of the armature shaft.
Motoring Department-My car had
the front axle badly bent, and since
having it repaired find the car sways
at speeds of from % to So miles an
hour. How can l find out whether
front axle and wheels are right and
how can tell whether front and rear
wheels track flames Bredie.
The swaying may be caused blythe
felloes of the wheels being bent. Also
note if front axle stands at right.angles
to the frame. To make sure the
wheels are lined up properly, measure
the distance from the rear axle to
the front axle on each side and see

other After doing this, point the
front wheels straight ahead and meas
ure the distance from rim to rim at the
back of the wheel and front. The rims
should be approximately equarter
inch closer together in front than in
rear.
If all the axles and wheels line ur
properly, there is no reason why they
should not track"
