FIRING TIME ADJUSTMENT.- In order
to set the firing time of the engine, it is nec-
essary to
ha
ve
previo
usly
ca
librated the
points. Once this
requirement
is met, the
engine's firing time is adjusted by the
fol-
lowing
process:
On the lateral surface
of
the magneto
flywheel there are two fine lines. In relation
to the way the engi
ne
revolves (shown by
an
arrow on the flywheel), the first line cor-
re
sponds to the firi
ng
time and the seco
nd
one to
upper
neutral. To set
the
engine's
firing time, make the first line coinci
de
with
the first line with the mark (zero) which is
on the machined outsi
de
of
the crankcase.
When the flywheel is in this
position,
the
points should be about to open, a condition
we achieve by loosening the screws which
hold the support disk to the crankcase and
by movi
ng
the disk in the direction neces>
sary to put the points in the desired position.
That is when it is about to open. Be especially
careful not to move the flywheel when loos-
ening the screws, and if it moves, put it once
more in the proper position before moving
the disk.
Once the time is set, tighten the
disk screws, being careful· not to move the
disk.
Check
the firing time again. (See fig-
ure No. 7.)
