Bogs off idle, any ideas?

When I press the throttle it has a BIT of hesitation. Any ideas on how I should tune the carb? It's an untouched Holley 4160 600cfm Electric Choke/Vacuum Secondaries. I think I have it pretty lean at idle, should I richen up the idle? Thanks guys!

If its boging at idle, I would have thought that that meant it was too rich.

A bad EGR valve will also cause a slight bog off idle.
If you have an EGR try to unhook the vacuum line and plug the line, then take it for a cruise. If it acts fine now, then its your EGR. If it still does it, its probly carb or timing related.

It may NOT be the EGR. I suggest you test it.
