528 Hemi help

The effect of air bleeds is not always predictible. The purpose is to correct the fuel curve on a fixed jet fuel system. Any emulsion is a just a side benefit. Too much air and delivery will be erratic.

Going too big in an air bleed will delay the start of fuel flow. Picture sucking on straw with a big hole in the side. Then it may go rich before settling down, and then will go lean. See the last post here for graphic

The idle system also has a variable air bleed in it. That's the portion of the transfer slot above the throttle blade. See this Chrysler tech booklet for the concept
