Is he running an electric fuel pump?  If so is it a 2 - 3 PSI unit or the higher, more common 5 - 7 PSI pump?  the higher pressure may be overcoming the float valves.

My friend's TR6 was running poorly. After the car had been running, and was turned off, I noticed drips of gasoline dropping from the port below the forward carb just in front of the intake manifold. I concluded the Gross jet was not stopping the flow of gas to the carb and gas was getting pushed into the engine. So I replaced both float valves with standard valves and also changed both floats. After putting everything back together, I ran the car for a few minutes and turned it off. It was dripping gas out the same port. Looked in the throat from the air filter side and saw a small puddle of gas in the lower area right in front of the venturi. As far as I know, that means the gas isn't shutting off. Perhaps I didn't adjust the float correctly. Or there is something at the fuel inlet orifice allowing gas to bypass the valve. Is there anything I am missing here? Could the enrichment valve  (choke) be the culprit? I haven't touched that yet. I adjusted the new float to fully close the valve when the mold line of the float was parallel with the horizontal edge of the carb where the fuel reservoir attaches.

Am I missing anything else here?

Thanks
