Wow...go figure. If it's in a 45 degree angle, the whole "theory" of engine
vacuum causing the sticking throttle is completely out the window (as with
closed, or any other position).
ANY of the modified, factory, or billet TB's will freeze up with nitrous
coming through it - heck, my old F&B did that (so did the factory V8,
Fastman, and APS 50mm's). The anti-seize will also wash off with a wet
system since fuel has a tendency to clean off lubricants.
Funny thing though - we run more than 60 TB services through the shop every
few weeks and NONE seize up, hang up, or bind due to cleaning. Heck, we do
hundreds every year without this issue - so obviously something else is in
the mix here.
On the bearing comment, some use a bushing, some are just a support journal,
and some use a bearing.
Again, look at the whole picture and try to think for a second - the TB's do
NOT hang unless there's something wrong in the shaft, bearing, or bushing
area (which includes TPS and Throttle Linkage). It's called diagnosing and
trying to figure out the How, What, and Why of the problem...which also
prevents it from happening again. Lube the throttle shaft - enjoy. It'll
come back - hopefully it won't hang up at a stop and cause an accident.

Wow, go figure. Bernd didn't have the right answer. And did you happen to
look and see if there was a bearing in the center between the blades?? If
the shaft is dry, it doesn't matter if it's in perfect shape, or not, there
is going to be extra resistance until you apply some sort of lubricant.
Bruce from F&B uses anti-seize because it resists freezing up with nitrous
use as compared to other lubes, and doesn't wear or wash off as easily.
