Hello again!
I switched the 3.5 PV back in. The idle readings went down to 13.0 to 13.6. Kinda odd for it to richen up when I went to a smaller rated PV. I turned the idle mixture screws in to where they sit at 1 1/4 turns out again and the A/F reading came back to the 14.5-14.9 range.

NOW it goes off the charts lean when I put it into gear or hold the brake and ease on the throttle.

I thought I knew a little about carburetors, but tell me if i have this right:
* The IDLE circuit works when the primary throttle blades are closed. The main jets are NOT in play when in the idle circuit.
* The primary jets begin to function when the engine is put under a load and the primary throttle blades open.

If the above is true, would that mean that my primary jetting is still too lean? I understand that you are supposed to make only one change at a time which is why I only changed the power valve when I had the bowl off.
Looking at the gaskets I used, they actually are fine. They are a rubber like red gasket that came in a Demon rebuild kit I had.
