The primaries have a metal float without jet extensions. The secondary side has a black nitrile float with cutouts for the jet extensions.

I was wrong earlier. The carb came with a 4.5 power valve. I am currently running a 7.5, not a 10.5 like I mentioned earlier. My motor idles at 13 and cruises at 15-18. I'll bump that PV up a bit to see if it gets rid of the hesitation part - throttle in the corners.

I have the dual plane Performer RPM but have a 1" open spacer. I haven't really considered a single plane intake.
