RICE RACING will become famous soon enough
This may be of interest to some people, I still like to look at spark plugs after a long drive or extended use at a new setting on the engine parameters generally half a dozen full throttle applications is enough to establish what is happening via colors etc.

For those not familiar with rotary engines: (leading plug holes have a large opening to the combustion chamber and trailing plug holes have a smaller shielded hole) I use this visual check + EGT reading to balance any differences in the fuel air balance.
FL = front leading spark plug
FT = front trailing spark plug
RL = rear leading spark plug
RT = rear trailing spark plug
NGK 10 heat range plugs are 2000km old, run a 0.020" gap, Optimax Shell 98 Ron fuel, Mobil 1 engine oil (oil injected into motor), and Sthil 2 stroke premix at 180:1 mixed in with fuel also
10.9:1 AFR with 1.20kg/cm boost and 500cc Water Methanol at 50/50 mix, engine operating temp is 77~79 deg C


In case anyone is bored! Look On !!!
