Here is my situation.
I have a stock 2.7 motor. It's old and worn and needs a rebuild but all I could afford right now was the top.( Carbs and ignition).
They are 40 PMOs with 34 Venturis, 135 mains , 55 idles, 130 idle airs,190 airs and F11 tubes.
I can't seem to stop running running rich. When I set them to a respectable 12.9 or12.5 they just wont run right.
I need to be in the 10s in order for it to perform properly. I can get away with an 11 AFR but that is about it.
What do you think I should change?
I know changing jets would be easy, but I was hoping for something even easier, like a float bowl adjustment.

You've posted some issues with your carb setup recently, yes? Remind us about that and perhaps a short summary of how you set them up.
As I recall, you ended up using the idle air jets to adjust idle mixture/speed. That right?
