I would be less disturbed by the 96,something% than the fact that kaminethanol burns with yellowish flame. alcohol/spiritus burns rather blue. that’s why I wonder what the ‘stir in’ for the beautiful yellow flame? one of the chemists here? not that I’m more upset with the motor than this bad petrol-plörre at meienr e85-tanke (one remembers the thread with the deposits around the intake valves) that’s the only thing that prevents me from placing an ebc at the moment.
