Convert to replaceable idle air bleeds?

Today I drilled and tapped all four IABs for 8-32, then installed .070"-drilled screws.
While I was in there, I also did the PVCR's which were huge (.070") especially for #70 (.073) main jets, and those jets give the proper cruise AFR. As a trial I did .052". May still be too much enrichment but at least now I can adjust them ;)
