RE: COX 049 Bee mixed parts.
Yep,leaky as all get-out until I learned the
"thread trick", many years ago.
Probably poured several ounces of fuel
through various engines before that.
Real tank screws(not the soft junk that came in the kit)
didn't hurt either.
This Bee does not leak!
Don't ask, I never timed it.
