Air bleed question, tuning with wideband

[CurtDawg510]

Ok... Its in my 70 duster, its got a pretty warmed up 360, 10:1, big cam, no vacuum
727, 2400stall, 3.55 gear...U kno...lol
The carb is a quick fuel race carb with annuler boosters, 4 corner idle
Im tryin to lean out the cruz a/f on the wideband
Shud i be increasing all 4 corners idle air bleed, or mainly just up front
I got the idle a/f dialed in, jus when im cruzin 1500-2000rpm

Im thinkin jus up front shud do it... But what you guys say??
Thanks people!

Oh duster donut videos are nice too!!
That fuel leak is fixed!

Oh ya, its Progressive linkage.... So im only tippin in up front when cruzin
Thats why im thinkin jus mess with air bleeds up front, and dont worry about the back
At least for this rich cruz thing im tryin to lean out

Think he means ifr`s.............idle feed restrictors which some call "idle jets" and those will lean out the supplied fuel to the idle circuit but I`d go .005 bigger on all four idle bleeds and go from there.
