One of the plug wires was bad, so i replaced coil. Now getting very intermittent spark. It fires a little bit on one side maybe every 5 kicks. I was thinking stator now... but all the resistances checked out. Could the stator still be bad? I am going to really look over the wiring. Also, for grounding I have heard of running a grounding strap. Should i do this, and if so, do i buy one from like an automotive store, or just use heavy wire?
