Why does fuel pour into air filter housing on 1984 Honda Prelude dual carbuerator when started?

yep, it's the needle and seat. It's the part inside the carburetor that shuts off fuel flow when the carburetor bowl is full. The needle and seat makes up the shutoff valve that closes the fuel supply when the float rises in the fuel bowl. If it doesn't shut off, fuel floods out into the overflow which typically dumps into the air filter.
