Well, I started with changing just the wires, nothing else.. and there might have been a little improvement. But then I just did what we all know to do... all of it. Points, Plugs, Condenser, Cap, Rotor, Set Timing, and a New Coil, just in case, along with the new wires. It was something in there, or a combination of weak parts, because now it runs delightfully smooth, just like it should. smile
