The vacuum can on your distributor is 90deg different from mine. But the No1 spark plug line looks in the same position. So I am curious, what distributor part number do you have?
I'd have to pull it to get to it.... I don't think I can get a photo of it. But it is the original, stock 1971 fuel injection distributor. Make sure where your vacuum can is, you can twist the distributor. If you are not in the same spot, ie toward the opposite side, it is 180 degrees off... you can't twist enough for timing possibly. All depends on the timing of the motor though so don't just pull it. The position it is in allows for a wide range of timing adjustment turn (not that you need huge swings). I'll take a look later today and see if I can get the dizzy number.
Ha, I was being stupid. You just have your No1 plug going to a different cap position, duh :) But I am curious what distributor model you have because it seems you have the dual vacuum and few people seem to like that. I have dual weber carb IDFs so a different setup, but am also running a dual vacuum distributor JFUDX4 (or a model 205) with electronic module inside.
