A Holley 2-barrel carburetor could be dumping fuel due to several reasons, including a stuck float, a malfunctioning needle and seat, or a clogged fuel line. If the float is stuck in the open position, it fails to stop fuel flow, leading to overflow. Additionally, dirt or debris in the needle and seat assembly can prevent proper sealing, resulting in fuel leakage. Regular maintenance and cleaning can help prevent these issues.

Why all the fuel is dumped by shuttle before Reentry into the earth's atmosphere?

I didn't know that it was - but I would imagine they would do so to reduce the weight of the shuttle so it does not re-enter the atmosphere too quickly. If the fuel is something like liquid oxygen it would have no ill effects on the atmosphere. == They dump fuel to reduce shuttle weight so it can decelerate faster in the Earth's atmosphere. It doesn't slow due to the dumping itself.
