armature plate. The ground wire for the
coil should be attached under the head of

core.

GOOD WORDS
All engines covered in this manual use
the same set of points (Part No. 580148).
The points MUST be assembled as they are

the base and is non-moveable. The other
side of the set has a moveable arm. A small
wire clip and a flat retainer are included in
each point set package.
9- Hold the base side of the points and
the flat retainer. Notice how the base has a
bar at right angle to the points. Observe
the hole in the bar. Observe the flat
retainer. Notice that one side has a slight
indentation. When the points are installed,
this indentation will slip into the hole in the
base bar.
