Check youtube, I am sure there is a plethora of videos on this subject.
12 volt neg ground or 6 volt pos ground? Choose a timing light that is compatible with your battery voltage.
Attach the power leads to the correct battery terminals. Clamp on the #1 spark plug lead. Start engine, point the light at the dot, pull the trigger and note where the light
is flashing relative to the dot. Advance or retard the distributor - move in a CCW or CW direction. Correct timing is 'right on the dot'. Put a drop or two of white paint on the
dot, making it easier to see.
Another way is to use a vacuum gauge. Adjust timing so that you have the highest reading, then back off slightly.
