TIMING (MAcsNET~) .
Timing
Magneto
Ignition:
For precision
timing,
use timing
light per instructions
furnished
by the light
manufacturer.
Do not connect
a battery
to the magneto
as this will ruin the coil windings.
To time
ignition,
proceed
as follows:
1.
After
making
sure breaker
point gap is properly
set,
connect
timing
light to #l cylinder
then
start engine.
2.
3.
Aim
timing
light into.pointer
area on bell housing.
SPK mark
should be even with the pointer
just
as the light flashes.
If it is not, proceed
with Step 3.
To adjust
timing,
loosen
(do not remove)
the two magneto
mounting
capscrews-shift
position
of
magneto
(top flange
eccentric)
until SPK mark
is exactly
centered.
After
proper
timing
is
attained,
retighten
