Continuing missing F-20 engine saga

Guys - - Some frequent readers have seen my pleas for help this past summer on my F-20. After all efforts to make this engine run smoothly, I still have not stumbled into the problem. The missing problem comes when the engine is running spark advanced and little or no load, at any speed. Spark retarded, it runs smooth. Spark advanced and under a heavy load, it runs great. Have verified valve and spark timing, swapped carburators and magnetos to rule them out, checked for vacuum leaks, new rings, ground & set valves to .020" hot, plugs & wires, and a bunch of other typical stuff. Still no effect. Several of us are baffled. I did notice the other day that each time the engine misses under an advanced spark, a light popping sound is heard at the intake of the carburator. There has never been any serious back-firing issue. Is my problem in the head ? What correlation does this popping sound have to the engine missing? Your thoughts please........
