Rotor seated on dizzy shaft all the way?

I'm curious what would happen if you swapped the plugs wires from cylinders 1 and 2, with 3 and 4. Note a difference? Then swap plugs the same way. I'd just want to rule out it wasn't either the plugs or wires before ruling it is the dizzy.
I just troubleshot a cross-firing issue with an HEI and some brand new 8.5mm silicone plug wires. Who wouda' thunk? (IMG:style_emoticons/default/confused24.gif)
Rerouted the wires, no more problems. (IMG:style_emoticons/default/smilie_pokal.gif)

Oh, and best of luck. (IMG:style_emoticons/default/cheer.gif)
