rwingsfan,
OK. Well, I think you have proven that the coils are ok. Here are a few suggestions;
1. Advance springs are too tight. Advance occurs late, so engine is sluggish until the advance finally catches up at a high RPM. Check with a timing light. Advance should go to max at 3,000 RPM.
2. Advance springs are too loose. Advance happens too soon and the engine doesn't run right until the RPM's catch up to the advance. Check with a timing light. Advance should NOT go to max before 3,000 RPM.
3. You may still have an electrical problem. Check the voltage at the coils with the engine running and all electrics on. Should be just a bit less than battery voltage, like, 13 to 14 Volts at 2,000 RPM.
4. If you have vacuum barbs, make sure they are either connected to the pet cocks or blocked off.
5. Air leaks in the carb holders.
6. Bad gas?
Hugh will probably be here soon with some more ideas, but try the above and report back if they don't help.
