Truck was sitting for over 10 years. Prior to that it ran great. I have replaced all the fuel lines and filters. Gas is clean. Was running like crap, but I rebuilt the carbs. It sounds a ton better, but now the carb closet to the firewall sounds like it is leaning out when you press the gas. Some hesitation. It sounds fine after you hold it for a second or two. Haven't played with any of the adjustments yet other than the throttle linkage, which looks correct.

Any ideas?

Here is a video of the engine sound I am talking about.
