Fuel smoke and fouled plug

Advance would not affect only one cylinder like that. Bad plug / bad plug wire/ carbon tracked/ cap cap might, but that is easy to "try."

I may try new plug wires since that’s what my budget can handle right now. I did a resistance check and all plugs were about where they should be ohms/length speaking.

Cap, rotor appear to be brand new. Haven’t checked the dwell spots that could be a cause too I think?
