SAL98 - I had a similar problem on my BME 95 that I had on my Hanger 9 Sukhoi. I was running the CH igniton on it also.
You can try this and make sure that it is not a grounfing issue.
Take the ground lead for the plu wire and get a hose clamp that will fit around your spark plug. Fasten the ground wire to the spark plug with hose clamp. Fasten it to the part of the spark plug that you put the wrench on to tighten and loosen your plug.
I know you said that everyone has an opinion but I am just trying to offer some help.
