Hi Ralph
So back to the original point. He has a 3W ignition that uses CM6 spark plugs. The CM6 does not have a resistor built in. Screened or not he MUST have a resistor in the plug cap. The resistor must be a very low inductance, which is not typical of modern carbon film or metal film resistors.

I have a C&H ignition with a shielded lead and cap for a CM6 plug. I don't think it has a resistor in the cap.
Works.
