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.
