Dan,
Although I have not been able to find even one A&P in the whole wide world who nows this fact, the fact is still true. The fact is that Iridium plugs are supposed to be set at .024".
How do I know this? I bought a Champion spark plug gapping tool from Aircraft Spruce. The tool has 2 gap settings. One setting is labeled "Large" and sets the gap at .016". The other setting is labeled "Small" and sets the gap at .024" (maybe .022", I forget right now). The real question is: What does "Large" and "Small" mean. Someone at Champion must know. The Champion reps at SunNFun didn't know. I believe that "Large" means Platinum and "Small" means Iridium. If anyone knows for sure, please tell the rest of us.
I am the only one who is gapping my Iridium plugs to the correct gap according to Champion. I am therefore not pushing the envelope.

Increasing the plug gaps too much can force the magneto output voltage (the so called "spark voltage") to find another path to ground.

One might be able to use a larger gap than specified when the ignition system is new but unless you know what your margins really are, you're not doing yourself much of a favor by pushing this particular envelope.
