Ultra HP carbs are set up for tuning. They have jets all of the circuits so they can be easily dialed in. If you have a wide band you'll be able to see what you're doing and can get the AF curve really nailed down.

A little off topic here but can tose holes be shrunk to cure a too fast idle?

I am not causing global warming, I am just trying to hold off a impending Ice Age!

If both the primary and secondary plates are fully seated and it will even idle, much less high, it is likely not the holes in the blades that are the problem. I would suspect a vacumn leak somewhere.
