Ralph,

The zenoah ignition also come with a black wire called ground wire which is usually lacking on other brand of EI.

So what you suggest is that remove the plug cap and connect the wire directly to the plug end and the braid (the metal cloth wire that wrapping the ignition wire) should be connected to the engine casing.

Did I read it correctly? What about all those comment is plug cap is a must to reduce the interference etc?

Thanks for the info.
