Convert to replaceable idle air bleeds?

DrCharles, you are correct, Pv circuit has nothing to do with idle vacuum (or affecting the idle). I tune mine to come in at a vacuum where I need the enrichment. Say like going from cruise to passing. Engine in my roadrunner idles at 6.5”, I run a 10.5 in it. There is always somebody that has zero understanding of the circuits in a carb that will argue this.
