Spark plug wire...solid or strand?

[mr.vrooman]

I have a '62 Evinrude Sportwin 10 HP. I just replaced the coils, points, condensers, spark plug wires and boots, fuel lines and rebuilt the carb.
I have 80 psi in each cylinder

After replacing my spark plug wires, I read in a thread you are supposed to use solid copper wires? I replaced mine with the same stranded 7mm type that was on it before..Is this a bad thing?

I put my spark tester on each boot and it jumps a 1/4" on each cylinder, but the spark is orange and blue, I wasn't too thrilled seeing that as I thought it should jump the 1/4" with a bright blue spark, but if you put a plug on it seems to have a nice spark.

My old coils connected to the spark plug wire by pushing in, the new ones were screw-in type, probably shouldn't have done it, but I pushed them in instead of screwing because the new wires were already in and I guess I was in a rush and didn't want to take it all apart.

It easily starts up, but sounds kind of rough as I change the RPM until I screw around with the carb and it sounds alright. I still think I need to adjust it more before anything.

Is this true about the wires? Should I be looking for solid wire?

Re: Spark plug wire...solid or strand?

Where did you get the wire? I just checked some wire I just bought from a Johhnyrude dealer and it is 7mm Hypalon stranded copper core. You say you replaced it with the same wire that was on it. If it was the original wire, it was probably stranded copper conductor. If it's running good, I wouldn't worry about it. The problem is when you replace the wire with modern auto wire with the graphite core.
