Very Rich ... Blow Through Setup ... Ideas

[Tim_in_NC]

Setup is a Solid Roller 383 with Procharger D1SC ...

Carb Hat and Carb are from SD Concept Engineering ...

My car is extremely rich at idle and under RPM load ...

Yesterday I was able to break out my LM-2 and get some Air/Fuel Ratio Readings:

I'm seeing 11.1 AFR at idle and then richer to 10.0 at 2K, 3K, & 4K RPM Loads ...

My fuel pressure at idle is around 6.5 lbs. ... with My distributor locked out with no advance, I'm at 36 degrees of timing and I'm seeing about 14 lbs. of vacuum at the carb at idle and then as the RPMs increase, it go up to about 24 lbs. of vacuum ...

Any ideas why I'm seeing such Rich Conditions?

I'm in contact with SD Concepts as well and hoping they can get me straightened out ...
