Craig, a couple of random thoughts. On my 48 this past spring it would idle fantastic but almost immediately bog down and run rough on throttle. Changed distributor, new wires, plugs, rotor. Thought perhaps fuel problem so changed carb, fuel pump, and fuel line. No difference. Running a NAPA coil. Replaced that and problem solved. Good readings on the old one but apparently once it heated up it started failing. P/N on that is a IC7 and you bypass the resistor as it has an internal one. Understand # 3 and 6 are the cylinders with the misfire? I'm sure you already have checked but recheck they are in the right holes on the cap. I almost did that on one of mine. I have a Charlie NY fully rebuilt distributor and a Skip rebuilt coil I could lend you if you wanted to try them.
