Diablo,
I never knew this. Why is it that more ignition MFG don't put a resister in the cap so that regular plugs can be used? Does the resistor break down in use? Wire wound vs composite would remedy this.

Try swapping plugs first to see if that makes a difference, it's cheap too. The CM6 plugs are not resistor. There's a resistor in each plug cap, perhaps one has gone bad. You can get a set of new boots from Desert Aircraft...$40. See if you can borrow an ignition from a buddy to swap and test.
