At idle right now the timing mark does it's weirdness on #3 & #1. On #2 & #4 it is steady so when I get home I will try switching the wires on 1&2.
To add to all of this, I noticed by accident as I reached across the top of the carb and inadvertently closed the choke with my forearm and as the idle increased the timing mark stayed steady. Don't know if that tells you anything or not.
If you closed the choke far enough, the engine should have died, but if it's running lean, and the choke closed slightly, this may have provided enough fuel to smooth out the idle.
Two things come to mind:
A) The linkages of the choke have a slight cam action when closed which raises idle speed slightly, which could smooth out the spark in the distributor and overcome a slightly
higher impedance in a plug wire or somewhere up the chain in the spark system (still symptomatic of a wire or spark plug which has higher resistance from the factory).
B) The behavior you described could indicate a lean fuel condition in the carburetor at idle. To fix this, the idle mixture screw on the carb needs to be adjusted slightly. Turn it counterclockwise to open it 1/4 turn and see if it changes things better or worse. This is not related to the spark condition, but fits the description of behavior you gave above.
You can get it dialed in by adjusting the idle screw either direction until the engine noticeably stumbles (either rich or lean), then re-centering the screw in-between the two extremes.
On another related note, have you put a vacuum gauge on the engine to visually diagnose what's going on? A good, steady needle around 20 inches of vacuum is what you want.
When switching the plug wires, if the problem stays where it is (#1, #3), the plugs need to be checked to verify the gap is correct. If the problem moves to #2 and #4, then the plug wires are suspect. Also, I don't recall seeing if you said you were using standard plugs or platinum, or something else altogether.
Keep feeding us information, and we'll keep trying to help.
