Is teflon gasoline resistant / proof?

I'm having problems with a carb float bowl leaking where it mates with
the carb body. It's one of those cheap 24mm OKO carbs I installed on a
Honda XR100. The carb doesn't have screws holding the float bowl to the
carb body. It has a spring steel wire that snaps the bowl in place. The
carb really made the XR100 come alive, as alive a XR100 can be anyhow.
So I'd like to use it if possible. That, and the first race of the
season is in a couple weeks, so I don't have much time to get another
carb and go threw the hassles of re-jetting.

I tried Permatex 2B, and Permatex copper head gasket sealant, but the
gas ate them away. The copper sealant held the longest, about three
weeks. I bought a tube of teflon thread / gasket sealant that is slow
dry soft set. It says it's good for all fuels, but is it really?
