Step up spring clarification? AVS2

It should tell in the instructions or may be download from Edelbrock's website. I just printed off the tune directions for my 1406's. I have glanced through the instructions but haven't studied. I did see a chart where it carb adjustments are in the center and it tells you what direction to go if you need rich or lean. It seems to be a bit confusing if you are just adjusting by the seat of the pants.
Thanks Mike: I talked to the Eddy tech line and the AVS2 tunes completely differently from the 1406. The tech I talked to recommended the rods I got and I bought the spring kit which has them all for $10 so its a no loose deal. They are working on the tuning charts for the AVS2 but they are not complete. I will just read my hot vacuum in park and go with the spring calling for that "of HG to start.
