... there is a pipe from the float chamber to the needle assembly hidden right under the carb.
The end that fits into the nut under the float chamber has a rubber washer round it to make the seal. when you take this pipe out, dig the washer out with a jewlers screwdriver and once everything is sparkling, and its time to rebuild.
Find a metal dustcap and have a look inside, the better quality ones have a chunkyer washer in the top which can be dug out, slip this over the pipe you removed after the nut is on the pipe, then push the pipe as far into the float boal as it will go, slip the washer up to the housing then slip the nut onto its threads, as it goes it will compress the washer and seal the connection. This sounds a lot easier than it is because there should be a spring round the pipe too which makes things tricky!

- good luck -

Oh yeah, a symptom of this leaking is; The fuel pump ticking excessivley when the ignition is turned on after the engine has been stopped for a while. Oh yeah and the fuel peeing all over the chassisleg next to the manifolds GULP

Are you saying your carb leaked so you replaced the jet pipe washer with one you found in a tyre dust cap?

You can also use a Morris valve stem seal. seems to work fine.

But are they resistant to petrol in the long run ?

Indeedy! I have considered the long term longevity of the washer but this one is farly fibreous so should last long enough till I get a chance to order the right one.
