Have a fresh rebuilt 6210 Holley,650dp with manual secondaries,and no choke.Rebuilt today with a complete kit.Installed it,got the idle mixtures set up,and took it for a drive.Cruised it around at highway speeds for about 30 mins,it ran great.Took down the Autobahn, and ran it about 2 miles at WOT.Afterwards it started surging badly at normal highway speeds.It's not flooding ,or dripping out the boosters,and it runs fine under acceleration,WOT or idle.Just won't hold a cruise with out coughing and sputtering.

What broke?
