unit over this can be determined. The
fact that your vibrator will not work,
clearly indicates an open primary cir
cult which should not be difficult to
locate The exhaust valves should
open approximately 30 degrees before
bottom center and close approximately
10 degrees past top center. The lead
given to valves differs on different
motors With this timing, however,
which is an average, you should at
tain fair results. The knock in your
motor is probably due to loose bear
ings.

have an auto that works as follows,
and wish your opinion on rectifying
the same. Magnetic will fire all right
when on level road and moving in
high speed, but when slowing down
and then starting, the car will jerk,
due to poor firing Cannot go up hill,
for il will slowly shut down to a stop,
but when throw the batteries on II
will fire all right Have put in new
wiring from magnetic, and am positive
there is no srCDnding-W. E NJ.
Would suggest that you have the
magnetic remagnetized: The magnetic
appears to give a good spark at high
engine speeds, but will not maintain
this efficiency at slow engine speeds.
The matter Of running well on the
level and not running well when on a
grade, should not be due to the mag
netO, ether than before mentioned. If
the motor acts well when running on
the battery system and does not act
well Wher running on the magnetic, it
is quite certain that the magnetic it
self is the source of trouble. The mag
nets become weak from various causes
and should be remagnetized occasion
ally.

On most cars I have noticed that
there IS what is called a sight-fsed
Ill
of this? Those I have seen have no
adjustments, and would like t. know
how the oil IN the motor can be regu-
lated by this--W- .. Burnett
The amount Of Oil is art regulated
or controlled in any way by this de-
vice It Is simply a device attached
IN conspicuous Place SO that tho
operator can readily observe the flow
of oil Most luhr5cati1r systems have
q pump GlIyen by the engine. which
pumps oil from the ], wCr reservoir
of the crank case % an Ubler cham
Der, where the connecting rods dip.
This oil is pumped through leads To
these upper chambers and then flows
back through a strainer into the reser-
Volr again being used again. The
sight feed is simply q break in the feed
pipe with a glass attached. so that the
operator can tell whether the oil pump
IS properly performing. This sight feed

Connect wire to each terminal and
immerse the ends in q solution of salt
and water. When the two bare ends
Of the wires are brought closely to-

form on the negative wire.

Will you please tell me why the make

orally used, and please explain this
SyStem2 I understand that a great
many foreign cars use the system

The make-and-break or low tension
system has long been discarded by
most American manufacturers. This is
due to the fact that there are
100 many working parts in this system.
Also to the fact that these working
parts are source of noise and trouble
It high engine speeds. Low tension
means low voltage and the term make ]
and break" simply indicates the make
Ind break of the electric circuit. This |
system as USED on auIOmODleS consists
II a low tension magnetic as q current
generator which are brought together
~ mechanical action. When the cleo
rodes come in contact within the
CYLINDER the circuit is closed and at |
he break away of the electrodes the |
electric arc drawn constitutes the
gnitiOn spark. The mechanical de-
ices attached 20 the make-and- break /
ystem are difficult to keep in per- 1
ect time in order to provide syn /
Erroneous ignition. A slight derange-
nent on any one cylinder will upset /
ne work OF the whole motor The /
high tension system, while more /
electrically, is less COM i
,icated mechanically. The electrical |
pplances have long since been very !
much perfected and accordingly give |
cry little trouble The majority of !
European cars use the high tension |
ystem- There may be a few using !
he make-and-break system. but these
n time will undoubtedly change.
