Carb leaking petrol

[L84]

Hi,
I have an old Harrier 41 307R
The gasket/rubber washer which is on the nut underneath the carburettor bowl has perished and fuel leaks from it. Just wondering if anyone might where i can get a replacement in the UK, or what size i need?

Thanks

Washer part number is Briggs 271716. Should be available anywhere Briggs parts are sold.
