a few
degrees;
then
turn rotating
magnet
in normal
direction
of
rotation.
Both
timing
lights
should
go

on
rotor.
If breakers
are
not properly
synchronized,
reset

q.
Check right
main
breaker
contact
for
0.016
.004 inch
point
opening
and torque
right
breaker
contact
securing

to
20-25 inch-pounds.
If
point opening
is
out of
limits, repeat
timing
procedure
setting
left main
breaker
opening
at .016
.002
inch.
If right
contacts
open
beyond
.020
inch,
set left
contacts
closer
to .018
inch. If
right contacts
open

looseness
in
the magneto
cover
of the
harness
assembly
and
for
any
physical
damage.
The capacitors
should
be
checked
for
capacitance,
series resistance
and
leakage.
Capacitance
should
be 0.34
to 0.41
microfarads.
The
use of
a Bendix
condenser
tester,
part
number
11-1767-1,
-2 or
-3 or
equivalent
will simplify
this
test. Replace
