HEI conversion problem - any input?

OK - here's what I have to report...

After sleeping on it, and thinking about how I had cheaped out on the dist and coil, I could only think what's wrong with myself in my head.
So I opted to purchase through Mancini a new distributor. I also opted for one of those advance limiter plates, it's pretty slick.
I also picked up a Delco coil.

So I replace, and double check my connections, and hit the key.
Fires up and dies out... much like I was fighting.

I had just rebuilt my carb 2 years ago, and was not giving it much thought to my problems.
The run condition was a sticking needle :violent1:
It would not let enough fuel in to idle more than a few seconds
Shortly after my flooding was the same issue.
I can't believe it but I had a fresh housing and needle in a drawer.
After airing out the cylinders, checking the oil and replacing my needle/seat the car fires up.

Now spins like a top.
Idles, restarts, cruise and throttle is great.
The mechanical advance limiter plate from FBO seems spot on too.

Thank you all for your continued thoughts and ideas.
I really can't thank you all enough.
