W5 headed stroker 12 to 1, We are runnin NGK with a heat range of 6 cause the plugs were too dark with 8s, carbon build up from idle time, It seems that we idle for around 10 min for every 3.5 second run time and that is not long enough to clean the plugs, so are the 6s too hot for this combo? fuel is 100LL and timing is locked @33 no bad signs yet detonation or pre

It shouldnt hurt anything... most it would do if you lean it out too much is stall it out(we are talking idle here) I have NGK 9 in my W-9 on E-85 14:1 but I think I am going 1 hotter on mine
