I believed in the past that this easy plug fouling was specific to my single rotor.
While tuning the carb, I am using quite a bit of rich mixture condition. Most of the time after a couple of restarts the game is over, and it doesn't start again. Also shutting the engine off for the day after running in rich condition results in not being able to restart it the next morning.
Taking the plugs out and cleaning them with wire brush and air is not doing any good. The only way I found is beat blast the plug all the way down to the base of the insulator. This works every time.
It is obviously carbon build up on the insulator. Why is it doing it every time? is it specific for the rotary? what is done in the RX7 done to prevent that from happening?
