Set the gap at .014 (book says .012 to .016), do this by turning the bolt head in the center (with a 17mm wrench)until the left set of points is fully open, then set the gap by using the 2 screws that attach it to the backing plate. Do the same for the right side.
Then turn the crank until the F mark lines up with the timing mark for the 1-4 set. Adjust the timing by using a multi-meter from ground to the points and adjust so that the meter starts to fluctuate (begining to open). Do this by loosening the 2 screw to the LEFT of the points.
Repeat for the other set, don't forget to line up the F for the 2-3 cylinders.
If you do not have the 2nd set of screws on the outside of the points then you ignition is from 1980 or later. In that case just turn the backing plate for the left side and if the timing is incorrect for the right side then you adjust the point gap on that side (be sure that it is between .012 and .016).
I just did this yesterday (correctly) after messing with it for about 4 hours on Sunday.
If you need a copy of the pages for this let me know.
Good luck
