If you film in landscape it's a lot more viewable on a PC (sorry, pet hate).

After much freezing of the video i'm pretty sure all your plumbing is correct. And that carb would appear to have no return to the tank so all you should need to do blank off your spare pipe.

You said when you ran it it filled the carb with fuel.
This tends to suggest either the float needle isn't seating properly which is a bit tricky to check without taking the top off the carb, and since yours is new and under warranty i wouldn't do that. Or that the fuel pressure is too high and it's forcing fuel past the closed float valve. One thing that controls the fuel pressure is the thickness of the spacer between the head and the fuel pump, i can see there is one from the video but how thick is it ?, can you measure it ?

In theory you can reduce the fuel pressure by putting a T piece in the pipe between the fuel pump and the carb, connect the side of the T to the pipe that goes back to the tank, but put a restriction in that pipe (something with a small hole in it) so that there is still some pressure built up.
But really, it shouldn't need that.

Have you mentioned the problem to Webcon, i think they were quite helpful last time i contact them, though, that was about 15 years ago.
