I would start by closing your secondary's more...and maybe your primary's too ?

How far out are you idle air bleeds ? Should be 3/4 to 1 turn out from seat for a baseline.

I know your eyes need to be burning with that reading

One thing at a time to see what is working and doing what.... too many changes and you're lost.

What RPM is that 10.4 at? What you do to change the AFR is completely dependent upon engine RPM, load and throttle setting. Different carb circuits come into play depending on what the engine is doing.

At idle and light cruise shoot for 14 or 15:1, even higher if the car will run well that way. At WOT most guys shoot for 12.5:1.
