Lean idle. Rich cruise.

Yeah I thought about that. But why in the crap did they put so many bleeds there i the first place? I can't imagine any benefit with 8 friggin holes on each block. I'm wondering if this is a WOT thing.......totally baffles me.

Because there are times when you may want to clean up the fuel curve a bit and moving an emulsion bleed can make a world of difference.

I had to use one of my tunnel ram carbs on the dyno for a friend and it made the most power with only one bleed open.

Moving that one bleed up and down will affect different parts of the fuel curve.
