Ok so I've been having issues with the bbc 454 running toooo rich, couldn't get the floats to set right, lots of carbon build up. Then today I'm looking on line for rebuild kits to give the carbs a fresh start

, and I noticed something very different about my Holley 1850 600cfm carbs--- they have two fuel inlets, so I keep looking on line and everyone else is running them with single inlets..... My question is has anyone seen this before??? and might this be causing my high rpm bogging?

feels like the motor is flooding at WOT... here's some pix... go back to single inlet and a fresh rebuild kit or?
