I haven't messed with the screws yet but thebowl levels are set right as far as I can tell taking out the side screw shows fuel levels right at the bottom of the screw hole
Well I'm hoping someone in your area can help you via this forum. Just getting it to idle is only one part of the whole picture. Just so you know all 3 carbs are part of the idle circuit. You now you can take the front and rear carb off and block off the intake and run the car just on the center carb. May help you troubleshoot. Unfortunately I'm not close (Michigan).
