Turn the alternator until the left point is as wide open as it gets.
Set the gap here to 0.013". Don't bother gapping the right point.
Hook up your little static-timer bulb, rotate the alternator until you feel/hear the left cylinder come up on compression stroke. If you stick your finger in the spark plug hole, you'll hear/feel a "swoosh" of air as you come to the top of compression stroke.
Rotate the entire point plate until the light bulb comes on EXACTLY at the "LF" mark.
Now turn the alternator and adjust the right point gap until the light comes on EXACTLY at the "F" mark. Don't worry about what the gap is on the right exactly - it is what it is, there's nothing you can do about it. Hopefully it's somewhere close to the right value.
Remember, set the left side timing by rotating the entire point plate - set the right side timing by adjusting the right point gap.
If you have a strobe, when you open the throttle, the timing should "advance " to somewhere between the (unlabeled) two marks.
You will get oil all over you and your little strobe light.
The photo shows a CB200 alternator, it has only one set of points/marks. Your alternator will have two sets of marks.
