I totally dig the NGK line of sparks but for this instance it seemed as though the plug was just a tad to long and would bonk the top of the piston. Sometimes rendering the motor us less. Now keep in mind my motor(which works great with the CMR6A) was purchased second hand and is probably one of the original GEOs which could be the issue completely.
Ps keep up the amazing work y'all.
