Crappy idle, misfire on one cylinder.

[DarrenX33]

Anyone one have any thoughts on this?

Plug 2 is not firing. All others look fine. I tried the following to get 2 to work..

1) plug swap 1 to 2, no change
2) new plug wire, no change
3) tighten up plug, no change
4) change cap, no change
5) change rotor, no change
6) change timing, no variation of timing brings 2 back.
7) change capacitor, no change
8) watched for spark on plug while grounding it. no spark until you hit about 1500 rpm, then spark is there but looks weak. Perhaps my spark is weak all around.

Distributor was just rebuild/restored by Jerry MacNeish. I have new plugs, wires, coil, engine harnesses. Totally stumped.
