To adjust, loosen the retaining screws
and
move
the
unit to ftnd
proper
gap.
If the
gap
cannot be adjusted, check
the
trigger
pins'
length.
The
short
trigger
pin
should
extend
.187"
from the mounting surface.
The long trigger
should
extend .250"
from
the
mounting
surface.
Remove
'he
flywheel and
drive the
pin(s) in or
out the required
amount.
d.
CoiI Lead.
Remove
the coil
lead
from
the ignition
unit
terminal.
Attach
leads from a standard
ohm-
meter to the
lead
eyelet
terminal and to
ground
to
check series
resistance
of the ignition
generator
coil. See Fig. 15.
1. If
resistance is
below 400 ohms,
replace
the
stator assembly
(which
includes the coils).
NOTE:
The
ignition
generator
coil
cannot
be
replaced separatelg.
2. If coil
resistance
is above 4(X) ohms,
the stator
assembly
is
working satisfactorily,
therefore
the ignition
unit should be
replaced.
