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?

No idea, but I'd guess that technology has improved quite a bit in the
last 30 years.
Long ago I got GE (I think) to send me a sample of some
gasoline-resistant gasket goo which I used to fill up the hole in the
top of the Dell'orto carb where the cable went through. It wouldn't
stick to the threads so I used teflon plumber's tape to take up the
slack in the now-oval carb (some ham-fisted previous owner decided that
'round' wasn't the right shape). The engine ran a little rich, but I
didn't want to take the carb apart again so I just let it stay that way.
Worked fine until I found the identical carb at a yard sale, brand
new, for (I think) $5. I wonder what real miracle I gave up for that
carb...

There is a stuff called Valflex liquid gasket. It is white and comes
in a tube like a toothpaste. It stands oil and gasoline, as long as
the surfaces are clean. I've used it with very good results on a
keihin carburetor, when I could not find a new o-ring and *had* to go
riding... :-)
Maybe the "valflex" brand is not available in U.S., but I am pretty
sure there is something else that is the same.
good luck!

Teflon is impervious to gasoline. I work for an oil company . . . we use it
on all threaded fittings.
