Yes, main body tapped for TSR.

As delivered it had: .070 IAB, .033 IFR, .081 TSR. Sounds reasonable but runs pig-rich (12:1 at tip-in, 10.5 on full t-slot)! Stinky idle too. No point in going back to what obviously doesn't work

First I tried going up on the IAB, that made little change as expected. Then going down on the TSR in steps which helps some. Now it's lean at tip-in and still 11.5 on full t-slot.
This problem exists on the old 4780-2 also, but less severe since it takes a bit more throttle to cruise with the smaller venturis and butterflies.

Sure, I am aware of misfires causing artificially lean readings due to unreacted oxygen in the exhaust.
Whatever the actual AFR is, I set the mixture screws for best idle which always turns out to be 13.8 on the meter and no eye-watering exhaust.
