Hey, got an easy one, the other night i went out racing at a local "public built" dragway. And I noticed a moderate amount of black smoke at high RPM. Never had it before I got the new Holley, so Im guessing I'm still running rich. Ive also noticed more carbon in the exhaust,,,,,need some thoughts.

If its too rich at WOT then jet the carb down some. If its good on the primaries then just jet down the secondaries. You could pull some plugs too, just to see.
