It appears by the photo that you just need to turn the crank clockwise a tooth for the marks to line up, does not look a tooth off.
When both marks are together, you are at the #6 firing position. When both marks are at 12 o'clock, you are at #1 firing position.
It is best to align marks together for a good visual, then turn crank 360º to be at #1 firing position and drop distributor in with rotor pointing at #1.
You can leave marks together, just be sure to drop distributor in with rotor pointing at #6
