To Ed Woods, Malcolm Walker, and others:
You really have to admire the creativeness of the Brits. They designed
carb float chamber vent pipes that were also intended to allow petrol to
overflow at times. Not only that, but the vent pipes were intentionally
located close to the hot manifold so that the lost petrol would vaporize
and wouldn't mess up your garage floor. Now, that's planning!
If this was done in a Murican car, a timer would have been built in so that
the vehicle burns itself up one day after the expiration of the warranty.

Summer,
They can call it "venting" if they wish, but if a float sticks or there is
too much fuel pressure, they will "vent" raw fuel all over the place.
That's
why the old MG's had "vent" pipes extending down below the manifolds; all
the way down to the oil pan. When they "vented" the raw fuel would spill
onto the ground below.
