The block in my buggy is from a 70 T2 and I've just replaced the 009 with the diz that came with the engine. I've determined that it is the correct unit for this engine and timing should be set at 0 degrees. When I adjusted the valves I made sure that the rotor was coming around to #1, and turned the pulley so that the notch lined up with the crack in the case. From here using the pencil-in-the-spark-plug-hole method I found actual top of the piston stroke to be about an inch to the right of the notch. I made a mark here and used it and a mark I made 180 degrees from it to do my valve adjusting.
Now I adjusted the points and statically set the timing to the mark I had made, an inch or so right of the pulley notch. Acceleration was poor, it was popping at idle, etc. I set up the carb using info here:
