JMHO, but appears you have two problems;
1). There may not be enough initial timing on the motor.
2). Appears the carburetor is suppling too much fuel to the idle circuits.

I would give it a...

This is true normally, because the power enrichment circuit operates via venturi vacuum (fuel is introduced above throttle blades through the boosters). However there are a couple of exceptions;
...

LOL!!! Been there done that!

OK, assuming all is good with the motor. This may simply be a big cammed motor and carburetor not set up for it. So lets try something very simple first and get the motor idling so we can go from...

QOUTE;
Hey guys, I need some help or guidance, I have a newly pro built 496 for my 1969 camaro, it was originally dyno’d by the company it was built by so it has been run.

1.) Pro built and ran...

I think the OP is playing a sick joke on us. No one would be this ------..........

Agreed, 7 psi is a little high, while the manufacturer may claim higher psi is OK, I, like you would not.

Also agree under normal circumstances this is the formula for power valve tuning, normally...

You are running way too rich at normal idle speed, your vacuum is way low at normal idle speed. Logic tells me your power valve is opening at normal idle speed because the vacuum is less than the...

34-40 has summed it up.
One caveat though, if you eliminate the power valve (which I don't recommend for the street), you will need to drastically richen WOT (wide open throttle) as the power valve...

Gently seat/shut the idle mixture screw (close, turn in, righty tightly). If the motor runs with the idle mixture screws shut it is getting fuel from somewhere else other than the idle circuit. This...

With only 6hg vacuum, I would be suspicious of the power valve opening and flooding, another reason I suggested closing the the idle mixture screws.

Denny, I read your statement as sarcasm, and due to a bad day over reacted, for that I apologize and will edit my last sentence.

No disrespect meant, but we know he has an excess idle fuel delivery problem. While I missed the "waiting on a gauge" part buried in solid block of text with no paragraph breaks, my bad. However,...

Can you close the idle mixture screws completely and the motor still run?

What is your fuel pressure?
