This morning I was reverting my Ivans jet kit back to OEM. After that was done I was checking the float height, there was none! The float was hitting the inside of the carb bowl. That might explain the overall richness and low MPG. The height as-is was 8.5mm, the factory service manual says 13mm height. Here's a pic of the difference between the two heights.
In the pic below, the first float (right arrow) is now adjusted to the correct height. The second float (left arrow) is at the original float height. All the floats were at that 8.5mm height.
