I've heard yes and no about float height but I think I'll do some adjusting there. Plus or minus 2mm is quite a bit of wiggle room.
I'm going to say the needles are too rich.

Put them side-by-side with the original needles and compare their diameter and taper.

The stock needles are a bit lean, but usually a shim or 2 will richen it up enough to pull strong and cleanly through the range.

Have you looked at your plugs lately for an overall mixture?
