For those of you who use the AR2592 spark plug in the Renesis, do you use the 0.6mm gap the plug comes with? I bought 8 of them some years ago.

I've been using the stock plugs (RE7A and RE9B) for maybe 100 hours by now. Experienced a brief 200 RPM drop on last takeoff. Wondering if it's time to change plugs. Or re-gap the stock plugs to what?

What can I learn by looking at plugs?

Best way to clean them?
