Perhaps I misunderstand, but did you change out the dizzy/mag cap and perhaps the wires. I also like the coil suggestion. Aside from those(which it could be as faults tend to show up under load) the mixture could be the issue as previously mentioned. But without obvious air leaks, I hate to suggest this, but is compression still good? Hard to think it is the carbs as it ran well for 2000 miles.
