Why would a carburetor flood?

Why does the head gasket fail on a Toyota 4Runner?
The head gasket, according to Advance Auto Parts, is essentially a giant seal. It separates an engine’s combustion chambers from the rest of the block. This way, oil, dirt, and coolant don’t get into the chamber and foul it up, and the engine runs properly. However, like any other physical part, head gaskets can fail.
Can a bad fuel pressure regulator cause flooding?
Unless it is leaking. then it can cause flooding. But usually if that is the case, setting overnight it would usually start OK, because the fuel would have mostly evaporated and dissipated by then. You may also have a weak fuel pump so then a bad fuel pressure regulator would be that much worse. IF everything is OK now then let it be.
