Quad carb setup information help

I like running an AF gauge.. it's not an end-all but it is a good tool for tuning dual carbs.. you'll know more exactly how it's running as far as their fuel mixture as opposed to just smelling gassy... I used the AF cage to get it pretty close during idle cruise and full throttle but reading the plugs is the ultimate... I use completely different carbs and had to drill holes in the secondaries but not before I ordered new secondary flaps just in case I screwed up...
