carb problems

The carb will almost certainly be leaking because the fuel level in the float chamber is slightly too high.
I suggest you have a quick go at cleaning the bowl, check if the toggle levers work freely, check that the needle is clean and that the float is not full of fuel. If this doesn't fix the problem and the car runs well (and the carb only leaks when the engine is off), i suggest just turning off the fuel as soon as you stop the engine.

It looks like the one on the left. And is a horizontal. I will give it go at cleaning it

If it is horizontal, then it is likely to be a Zenith 26VA like this..
The images Dave posted are of 'updraft' variety. I think you shoud post a photo of your carb, so we can all be certain what we are talking about...

It could be an earlier Zenith, like this:

This is a 30mm on an Austin 12/4, but I've had a Seven running on a 26mm version (possibly from an early Riley Nine?).

sorry but i cant find any pics of it and i cant take any. i have already put the car un storage much to my shigrin. because here in Tahoe it snowed 1 foot of snow in October and rained for a few days straight. i can try to take pics next time i get to it but i know that this thread will probably have disappeared.

The thread can always be revived if and when you add another post to it. I fear we can offer no further help without photos. We are working in the dark
