At WOT, AFR is at 12.8-13.3. I went from the pink that the carb came with, to the blue with a very positive change, but I might change again to the orange cam. If I didn't have the wideband O2 sensor and just went by "seat of the pants" feel, it's damn near perfect for my grandpa driving style.

Fixed it for ya!!!
