I have a freshly rebuilt quadrajet sitting in my garage that has the same thing- runs, idles, starts all good- but ran rich on the small block that it was on. I tried 3 differnt needles, I got it to were it wasnt running rich but it ran worse. I just took the carb and factory aluminum intake off and replaced it with a Holley 670 and a cheap ebay polished Pro Comp intake. Now after a little tweeking on the Holley it runs great!
