I will have to double check the A/R at 3500-4000 but I am pretty sure it is 11.5 to 12.5. The high speed air bleeds are fixed. Were are these idle feeds located? I have the billet metering blocks.
If it's that rich I'd pull two jet sizes out of the primaries and recheck. Do this before you mess with the ifr's. Changing the primary jets will affect the cruise afr's, at least it does on mine.
What Ultra do you have? I thought they all had screw in air bleeds.
