When I was running .031 idle feed restrictors my plugs were fouling at idle it was so rich. I have 3 .028 idle feed restrictors but I broke the 4th one so I need a new .028. What size of idle air bleeds should I run when I swap to the .028 idle feed restrictors? .070's? or .072's? This has me confused. I even dropped the idle air bleeds down to .065 from .070 and it didn't change the lean condition with the hedders.
