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?

IMNSHO: Get thee to an Ace hardware or auto supply store that sells paper
gasket material and roll your own. You can also buy O-rings but I hate round
O-rings on a retangular bowl.

I would also check flatness of the bowl by sanding it lightly with emery
cloth on a flat surface. You may have a high spot where one of the corners
bent.

I've also had problems with the corners folding over on the carb body. Kind
of hard to explain what I mean and I am not sure if your carb even has them,
but kind of like a socket that the bowl fits into to align it. I've dropped
them and folded over the metal to the point where it was just about
impossible to seat the bowl while the carb was on the bike. Good luck
bending them back out if this is the problem as it seems as if they are made
to break.
