agreed, i have one of these 1.45" 950 carbs and i went from 78 to 72 (expecting it to be lean) and ended up getting back up to 74 or 75 to get the cruise happy. stepped downleg boosters.
this is on a mile 360 with the normal stuff, headers, airgap intake, good compression and semi lumpy cam...

i would get the cruise jetting in the range needed then go back to try to fine tune the IFR and TSR and bleeds. i made a spreadsheet to calc what PV area i needed to get the whole primary side jetting area with the smaller jets to equal what it was with the baseline jets..
