no, you could swap the wires if you also swap the wire that powers them up. These engines are 270 deg. fire so they are not top dead at the same time. I was talking about removing them both and swapping sides but you could just swap both sets of wires and see if the problem switches sides. To be clear when I say both sets I mean the 2 sparkplug wires on the one end of the coils and the wires on the other end of the coils that power them up to maintain proper fire.

I learned all I need to know about life by killing smart people and eating their brains.
