Gary,
I had an easy time using a dremel cut-off wheel to make the back-cuts on the
flutes to get it to cut toward the shank. It was easy enough to do by hand. I'm
not sure I would shell out $80 to have it professionally done, though I am sure
the results are "better". If I were going to spend that kind of cash, I would
look into getting a real piloted reamer. Joe Curto apparently supplies them,
but when I enquired about purchasing one, he didn't seem thrilled to sell one.
It seemed as if he didn't have them on hand ready to go.
A more cost effective solution would be to strip the carbs, then send the
bodies to Joe for bushing installation alone. I believe he quoted me $25 each a
few years ago for just the bushing work. Shipping would be on top of that.

Randall sent a link to a good article concerning reaming your own carb for new
bushings for throttle shafts.
One suggestion included grinding the cutting edges of the flutes on the reamer
to make them work in reverse. I'm not familiar enough with reamers. How simple
is this? I'm guessing that it involves grinding one side of the cutting edge to
make a "burr" on the other side of the cutting edge?
Is the cutting edge of a reamer sharp and angled one direction (which needs to
be changed the other direction by grinding?)
Or is the cutting edge of a reamer square with a little angle?
It looks doable to me and hopefully I can start soon.
