center, between the compression and
lower strokes.
4. Retard spark-control lever fully.
5. Determine which segment of the
distributor is No. I. This will be the
lower eft hand one, when the dis
trbutor brush revolves in clockwise
direction, and the lower right hand
when 1t revolves counterclockwise.
6. Turn the magnetic shaft in the d.
rection Of rotation until the dstrib-
'utor brush is approaching segment No.
q, then look at the interrupter points
and continue to slowly turn in the
shaft. in direction of rotation, until
the 1nterrupter points just begin to
open.
:. Fasten the shaft, being careful
not to change the setting and also be
certain that the distributor brush is
in contact with segment No I.
8. Connect the secondary cables to
the spark plugs in the firing order.
There IS one difference in the in
etruction as given above, and the in
struction for timing as given by one
of the magnetic manufacturers, name
~, in the fact that have told you
to set cylinder No. l. at top dead cen.
ter, and spark fully retarder. while
The magnetic makers instruction is to
set cylinder No 1 about one-half to
five-eighths Of an inch Of piston travel
before dead center and to have the
spark lever fully advanced.
Where the flywheel is marked by
the manufacturer Of the car or engine
with an M" or 'Magneto.' then the
advance setting should be used, as
when the mark NJ is on top. the piston
will be about one-half inch before dead
center If, however, you do not have
this guide, YOU will find it almost i'm
possible to set the cylinder the proper
distance before dead center, and I
would then use the retard setting.
Lever Not Advanced.
Note that the lever is not slightly
pdvanced as it is with the distributor
system. This is because the magnetic
has what is known as a lag, SO that
the spark actually comes slightly after
the interrupter points open.
large proportion of the magnetos
have the distributor plates designed
AS shown in Fig. No. I. Obviously,
II would be bad practice to cross the
wires running from the segments to
the binding posts on top, and these
wires. will. therefore. be cast in the
plates, as shown in the dotted lines.
From this YOU can readily reason
why. when the brush revolves in a
hand segment is chosen as No. !.
The figures on the top of the wires
give the cylinders to which these
wires would be connected were the
firing order l, 5, 3, 6, 2, 4.
Care of the Magnetic.
While Let it alone" is good advice,
as regards the magnetic. | give here
ssome of the things which may have
NO be done to it once in long while.
THE magnetic needs but little oil. one
or two drops of a very light oil about
,onCe in two weeks, in each oil hole
generally being sufficient. In this
respect, | might say that electric In
uruments generally must not be
& iven much oil, as the oil may work
& eto the instrument and so cause a
a hort circuit
Occasionally the distributor plate
Should be removed, and wiped with a
81 9th moistened with gasoline. Should
