What does the plug look like? Fouling? What is the gap between the rotor and body when it's at the #1 plug? Is it different than the rest? What is the point gap? Was the distributor rebuilt with the engine? If not how much side play is in the shaft?

As you can tell, there are a lot of things that could affect the plug firing, most of them are in the distributor. Was the sensor you were using an inline spark tester?
