If that’s the case drill them out to as big as you can so it’s no longer a restriction and just leave them in there.
Then I would drill out some 6-32 set screws (you’ll need 8) to .026 and get the idle air bleeds at .068 to start. If the idle is rich or lean you can adjust it by changing the IAB either smaller or larger depending on what you need. It‘s way easier to get to the IAB’s.
Thats AWESOME that you don’t have the 3rd circuit. That makes it way cheaper and way easier to fix.
