FWIW, my local O’Reilly Auto has 7mm stranded copper-core ignition wire for $0.69 / ft. They stock it on 100′ bulk reels, usually back behind the counter in the stock aisles.
This is the same material a lot of folks call "solid core" wire, despite the fact that it is stranded. In this case, I think they mean ‘solid copper’ (strands) vs. the graphite-impregnated fiberglass core used in most all automotive applications. For conventional, old school magneto or battery-coil ignitions (as on most motorbikes, small engines, etc.) you want a copper-core wire. If there’s any resistance to be inserted, it’s usually integrated to the plug cap – such as the NGK LB05F – which incorporates a 5K resistor.
Speaking of, I found a nice deal on eBay for NGK plug caps with NO resistor.. about $6 / pr. shipped, eBay item – 311274692919. Probably about the best cap you could ever have for an OBM / small engine. They seal out the water very well, and have very low dielectric leakage.
Nods to supporting your local independent dealers, but in a lot of places, they are already long-gone..
