So, I have a 1971 squareback 1600cc. It used to be fuel injected but since been converted to dual carbs. It was running right for a year or so but since it was shipped to Va, it has this issue. When accelerating it seems fine, but when I try to maintain a speed, say 35, it surges. Checked for vacuum leaks, carbs are adjusted, valves are aet correctly. Set timing, replaced points and condenser. Not sure what else this could be. I'm going to test the spark plug wires and the distributors connections to make sure they are good, but any help would be nice. Thanks all.
