Yes we can try on changing mix strength and ignition timings. We're working on it. Thanks for advice.
We have a double pass radiator with dimensions of about 9"*11". Shroud leaks as of now, new design on the way.

But would like to know if somehow we fail to get the engine temprature down below 116deg, will it still be fine to run it under theses conditions?

(Not to mention that only a few spikes of 116deg were seen, the average temperature in the log was about 104deg celcius.)
