There I was pulling off the performance of my lifetime at the Manawa mudfest this past Saturday when my front tire goes flat. This was totally unexpected since I run Stan’s NoTubes. I immediately realized that it wasn’t a puncture, but a leaking valve core. I have had this problem once before, but the air loss was minimal. This time I was not so lucky.
I used my CO2 cartridge to air up my tire, but it went flat again by the time I reached the finish line. I have since learned that Stan’s recommends periodic cleaning of the valve cores:

Ideally, it would not be a bad idea to replace them whenever new tires are put on or when rotating the front with the rear. Oh, but what a discouraging letdown, to have a great performance nixed because of a $1.98 part. So, Stan’s users be forewarned, keep those cores clean!

I say you just just runnin' dem thar hard rubber tubes, don't have to much worry bout flats with dose things.
tip to you all:
when running tire sealant, deflate your tire with the stem at the top of the wheel, pointing toward the ground.
otherwise, the sealant treats the valve like any other leak. it seals and clogs it up!
Thanks for that excellent tip--it makes perfect sense!
