Given that you didn't ask about the value or lack thereof of tubulars
and got that debate, anyway, I'll try to answer your question without
the debate.

Yes, carry a spare.

Yes, your spare should be pre-glued. Best if you ride one a bit, take
it off, and use it as your spare. If you repair your tubulars, one of
those is perfect as a spare. (I used to use a place called Tire Alert
to repair mine in batches, but I've ridden little enough and have enough
spares that I haven't had to use them lately.) If your spare is _not_
preglued, you'll still get a little adhesion but not much, and you'd be
best to take it easy when braking and cornering. (Yes, I've done this,
but only on a training ride, yes the tire rolled some but not enough to
hurt me or it.)

I always folded mine up and stuck it at the back of my saddle, sitting
mostly between the rails and sticking out the back some, held in place
with an old toe strap and usually a rubber band or another toe strap to
help keep the tire folded.

A previously glued spare ought to hold pretty well, let's say almost but
not quite as good as a freshly glued tire.

Hope that helps.

Oh, rec.bicycles.tech would be a good place to ask this one, IMHO, so
I'll add it to your list.

Carefully packaging that spare is important because jiggling under the
saddle can wear through the sidewall and furnish a blowout in waiting.
After folding the tire in fours, tightly wrap it in a brown paper bag
and secure it with a foot strap under th saddle so it cannot wobble.

If you ride tubulars, you will soon have enough spares and these
should all have been well glued, meaning they retain about half the
rim glue which is enough to make a well glued tire when changed.
