Edelbrock dumping copious amounts of fuel

Damn, what happened to all the carb gurus?

Well the Edelbrock tech seems fairly confident that the problem is too much fuel pressure, but I'm not so sure. Unless my fuel pressure reg is prone to catastrophic failure. Although I don't actually have a gauge, just one of those Mr Gasket regs with the preset notches on it.

He also suggested sunk floats,debris in the needles & seats, or low manifold pressure causing the metering rods to stay open.

I didn't think it would be sunk floats, high fuel pressure, or low manifold pressure because the car was running fine just previously. I think those issues would have shown progressive symptoms.

Today I took the air horn off to look for debris and check the floats. I didn't find any debris and the floats are not busted. So I put the carb back together.

Then I just simply tried to start the car. She did start and run. I observed the carb for signs of flooding again, but it didn't happen. She ran fine, I let her warn up and then shut it off.

If the fuel pressure regulator had failed, did it magically fix its self? I think it must have been some debris holding the needle open.

Discuss.
