RobinHood Kit car- petrol coming out of carb

[marksal]

I brought the car last year and took the engine apart.

It is all back together and I thought I had everything back as it was.

But today i tried to start it and had fuel flowing out of a tube from the carb. see images attached where my finger is.

I took picture when I first brought it so i could make sure everything went back. The guy i brought it from had just put the new carbs on. Not sure what they are?

I thing there should be a pipe going to somewhere??? Any ideas/Help
