Carb Tuning - Richer? Leaner?

[protour73]

Jody and Dale, you guys were right on!!

I switched to 76 jets from 74's, and jumped up to the 8.5 power valve and it's damn near perfect. At cruise now AFR is at 14.3 to 14.8

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 driving style.
