CRITICAL WORDS
As the coil, condenser, and "kill" switch
wire are being attached to the point set,
take the following precautions and adjust-
ments:
a- The wire between the coil and the
points should be tucked back under the coil
and as far away from the crankshaft as
possible.
b- The condenser wire leaving the top of
the condenser and connected to the point
set, should be bent downward to prevent the
flywheel from making contact with the
wire. A countless number of installations
have been made only to have the flywheel
rub against the condenser wire and cause
failure of the ignition system.
c- Check to be sure all wires connected
to the point set are bent downward toward
the armature
plate. The wires MUST NOT
touch the plate. If any of the wires make
contact with the armature plate, the igni-
tion system will be grounded and the engine
will fail to start.
16- Connect the wire leads to the set of
points.
Repeat all of these Critca1 Words for the
second set of points.
GOOD WORDS
The point spring tension is predetermin-
ed at the factory and does not require
adjustment. Once the point set is properly
installed, all should be well. In most cases,
breaker contact and alignment will not be
necessary. If a slight alignment adjustment
should be required, CAREFULLY bend the
insulated part of the point set.
ASSEMBLING 5-23
Before setting the
breaker
point gap, the points
must be properly aligned (top). ALWAYS bend the
stationary point, NEVER the
breaker lever.
Attempting
to
adjust
an
old worn set
of
points is not practical
because oxidation and pitting of the points will always
give a false reading.
Point Adjustment
17- Install the flywheel nut onto the end
of the crankshaft. Now, turn the crankshaft
clockwise and at the same time observe the
cam on the crankshaft. Continue turning
the crankshaft until the rubbing block of the
point set is at the high point of the cam. At
this position, use a wire gauge or feeler
gauge and set the points at 0.020" for all
models covered in this manual. A wire
gauge will always give a more accurate
adjustment than a feeler gauge. Work the
gauge between the points and, at the same
time, turn the eccentric on the armature
plate until the proper adjustment (0.020") is
obtained. Rotate the crankshaft a complete
