The only time that a regulator will make a difference on how the engine
runs is if you have so much fuel pressure that you're overpowering the
float's ability to close the needle against the seat. When that happens
you'll have fuel pouring out of the top of the carb. If your situation
is borderline then this may only happen during sudden transients such as
when you drive the car in an autocross, and you might have an
unexpectedly high fuel level in the float bowl, which would affect the
tuning. I forget if the Edelbrock has an external sight glass, but if
you can figure out where the fuel level should be in the carb (based on
the float level where the needle and seat just close) and then compare
it against where it actually is, you'll know whether or not the fuel
pressure is okay for the needle and seat and float combination.
Black smoke on stationary acceleration is either misfiring, or it's
because the accelerator pump is squirting way too much fuel. Rich
running during part-throttle cruise requires messing with the metering
rods. But you should first of all make sure of the needle and seat
situation, because nothing is going to work properly until you have that
set properly.
