erratic spark-copper wires ok to use?

[CamaroMan]

Hi all, so i checked timing this evening and #6 is perfect, stayed fixed on the 8 mark. #1 flutters about - changed the plug wire but still doing it. I cut and crimped wires but considering buying a new set.

I read someone had the same issue with alot of $ thrown into new ignition parts all round, went and bought a set of copper plug wires and same symptoms went away.

New timing chain, new dizzy and all ign parts. Only wires are not new. Same happened on another dizzy so everything is points to plug wires - are copper ones ok? I also set the gaps at 0.35 2 months back and they plugs are all burning a tan brown from tip down the core -

thanks

is feels like it surges ever so slightly anywhere form idle right up to 3500 -

Copper is fine. I prefer silicone, it's less 'noisy' (electrically)...

thanks chris i get what ur saying.. im gonna get R plugs - i think the noise is throwing my garmin fish finder off..

I solved my issue, it was the cable routing! after studying a few pics seems adjacent wires should be routed away from each other and not grouped and tidy - fixed it and she doing well..

Just odd still that #1 timing is at say 8 and #6 at 10 :/ everything is new, possibly bad qc?
