4. Turn the flywheel to the left, against crankshaft rotation, until the
timing mark is about two inches past the 25
0
mark on the gear cover;
5. Turn the flywheel slowly to the right and note whether the ignition
points just separate when the mark ontheflywheel aligns with the
correct degree mark (19
0
or 25
0
)
on the gear cover. If the marks
align as the points break, timing is correct. If they do not, loosen the
breaker box mounting screws and shift the whole breaker box assembly
slightly toward the air cleaner to retard the timing (points breairing
too soon), or shift it slightly away from the air cleaner to advaricethe,
timing (points not breaking soon enough) .. Tighten the breaker box
mounting screws securely after making an adjustment. Refer toihe
illustration, Ignition Timing.
To accurately check the time at which the spark occurs, an automotive
type timing light may be used when the engine is running.
To accurately check the time at which the spark occurs when not run-
ning the engine, connect a continuity test lamp set across the ignition
