Doug I cannot figure it out, but we have had a REALLY bad experience(s) with the platinum plugs. I had a new set of Auburns that worked great for about 200 hours in my AEIO-360s, but when we tried to run them in the AEIO-540s they started shorting out and fouling like crazy. They definitely work badly in the bottom plug holes and seem to short out with such high frequency we exchanged or tossed them in the trash. Apparently, the iridiums last forever but might demonstrate some of the same poor performance on the low end idle. Right now I use REM38Es everywhere and have had much better experience all around. We use CHAMPION SPARK PLUGS to support the team, but would in fact buy them anyway. Immediately after starting and until takeoff we lean the motor to almost a cut off point on the ground. Basically peak power. Try your mag checks leaned like this, and the problem may disappear altogether. By the way, you cannot detonate a motor at low power on the ground, so do not worry. This procedure keeps the plugs cleaner for sure. Kurt
