You know, Frank, you may have given me an idea. At idle I seem to be running awfully rich. I run a pair of Holley #8007 carbs on a Price Motorsports dual quad intake. I wonder if it is because I have the idle screws nearly closed all the way to get the idle down to 800 RPM since I have so much vacuum advance at idle (24 degrees) plus initial advance of 10 degrees. I'm going to dial back the adjustable vacuum advance to 12-14 degrees and then open the idle screws on the carbs to bring the idle speed back up. Let's see if that helps some.
