AVS2 carb tuning. Anyone with experience out there?

I have moved the accelerator pump to the heaviest setting. I have also tried adjusting the secondary air door all different ways. I have not found any instruction on how to properly set the tension on that air door.
what is heaviest? If you mean closest hole to the pivot, and re synchronized the starting point then, I get it.

What speed and rpm is it laying over at, and do the tires spin?
