Hi again Francois!
Now it's all perfectly clear!
I had imagined that the fuel pipes had to be connected to the two coming out of the carburetors but it wasn't clear to me where, because I saw that in some other kits those cables went around the engine and didn't stay on the left side of the car. I'm sure that your position is the right one, I've seen some old photos that clearly show that the cables run along the left side of the chassis. For the rest, I will connect the battery wires to the starter, as you suggest: by the way, I think there were two batteries in the old Bentleys but I'll see how to do it.
Thanks a lot, for sure I'll follow you in your current and next projects.
A.
