When making a jet change to fatten up,when do you change an air bleed VS fuel jet.I'm at 99 square and still lean.Does the high speed air bleed change the entire fuel curve??
The car is finally responding to small changes and I think I'm close to being dialed in
Yes, changing the air bleeds ( lo and Hi ) will move the entire fuel curve up and down. If you are trying to address an off idle lean condition, smaller hi speed air bleeds can address it, but you may have to drop jet sizes to keep from being too rich at WOT. Hard to get it all correct throughout the entire engine operating range without a A/F gauge. I have a A/F gauge and still have a hard time keeping the A/F in the range that my set up likes.
