reconnect it to the blue/red wire (PTO. side) leading
from engine. Rotate crankshaft until PTO. side piston
approaches top dead center. As soon as timing marks
align. timing light should fluctuate, or tone signal sound
level should vary. If necessary to adjust, proceed as
follows:
e If timing is too early decrease breaker points gap
toward lower limit, i.e.
0.30
mm
(.012"),
then
r.echeck timing.
e If timing is too late increase breaker points gap
toward upper limit, i.e. OAO mm
(.016"),
then
recheck timing.
