It's still probably way rich on the bottom end. They come that way to ensure a sloppy rich break in. Continue leaning the bottom end out as it breaks in. When you get it too lean it will idle great like a sewing maching but then will die when you hit the trottle hard. At that point compromise and richen it up just a bit to retain the transition to full throttle without dying. As it breaks in even more you may be able to lean out the bottom end a bit more.

If you want to know where you are at in a hurry now, pinch the line to the carb while it is idling. If it speeds up considerable then you are still way too rich!
