Fig. 3-19 0·200 Breaker Point Adjustment
Under normal operating conditions, a certain amount
of buildup or metal transfer between the point surfaces
will occur.
If this occurs too frequently and becomes
excessive, the condenser may be at fault.

The points are located on the top of the front side of
the engine inside a breaker box.
To check the breaker points, with a cold engine, re-
move the two nuts holding the heat baffle to the top of
the engine and remove the heat baffle. Use the following
procedure to check and adjust breaker points gap.
1. Remove the two screws and the breaker box cap.
2. Remove the two spark plugs so the engine can be
turned by hand.
Check the condition of the spark
plugs at this time.
3. Turn the engine over until the breaker points are
fully opened.
4. Check the condition of the breaker point surfaces.
Always replace burned, or pitted points. Dirty or oily
points can be cleaned with a cloth, but make sure no
particles of lint remain between point surfaces.
5. If point replacement is necessary, replace the breaker
points with a new set. Adjust point gap to an initial
setting of .023 inch (.6 mm).

6. Remove the air intake hose that connects to the
blower housing. This provides an access to viewing
the timing mark.

7. Check the ignition timing by connecting a continuity
light across the ignition breaker points. Connect one
lead from the light to the negative side of the ignition
coil (terminal that leads into the breaker box to the
breaker points). Ground the other lead of the light to
a good ground on the engine.
8. Turn the engine crankshaft counterclockwise until
the points close.
The light should now be on.
9. Slowly turn the crankshaft clockwise.
Adjust the
point gap so the lamp goes out as the timing mark on
the flywheel aligns with the 25

center) mark.
