there's some good info on the bicycles-faq list. Just goto: http://www.faqs.org/faqs/bicycles-faq/part3/ and scroll down to: Subject: 8b.20 Gluing Sew-up Tires

also... check out the Cyclo-Pedia article on tubulars http://bulgier.net/pics/bike/catalogs/cyclo-pedia-74/ in particular, check pages 31 to 34. (hey Mark, any idea why these gif files aren't showing up on my IE browser??)

Generally, I'd remove the old glue if it's that old. Apply a light layer to both the rim and tire, let them get tacky, slap 'em together & straighten the tire, and let it cure for a day. "Too much glue" is when it starts oozing out and onto the rim sidewalls. "Not enough" is when it's not difficult to remove the tire. (disclaimer: these are my thoughts, and I have limited experience with tubulars)
