With reference to the dripping 26va carb, I too suffered from this intermittent problem. A search through previous posts found several possible causes and remedies, none of which were 100% successful in my case. My car has a scuttle tank with fuel pump and I reasoned that the force provided by the float on the needle valve was borderline in opposing the force generated from the pressure in the fuel line. My solution was to fit a needle valve with a smaller seating orifice, 1.3mm instead of the standard 1.5mm, thus reducing the opening force acting on the needle valve. This has cured the problem completely.
