The needle valve in the carb evidently is not seating and allowing way too much fuel to continually enter into the fuel system. Remove the carbs float bowl to check for this. Float pushed up...should be no gas flow...float hanging down..gas should flow. The needle valve is probably either sticking open or debris in the seating area is not allowing it to seat (which shuts off the gas flow).

1991 toyota 3L V6 Overfueling, raw fuel pouring out exhaust pipes


The valve cover gasket change is related only to the extent of needeing to remove something else . There is the fuel pressure regulator and the MAF SENSOR talks to the ECU telling the computer how much fuel is needed for proper mixture of thre air passing into the intake. It is the first sensor in the intake duct coming out of the sir filter. Make sure all the injectors are secure in wiring connection and look around for any other that had to be removed. All plugs mean it isn't just one injector. Unplug and replug the MAF. cHECK THE THROTTLE POSITIO SENSOT. iT RIGHT THERE where the fuel likage is attached.

Not getting gas to combustion chamber, leaking gas from exhaust


Definitely the carburetor. Take it off and look for something clogged. Look carefully at the gaskets. Look for water and dirt in the float bowl.
