You need to go back to race fuel (we'll maybe not 114), or a mix. Those cranking compression numbers aren't telling the story. And I wouldn't change anything else......yet. You need to get the fuel right first. What do the plugs look like now.?. Are the pistons a dome style? Since we cant see all the increments of each run, and have no weather data, what happened exactly on those following runs? Was it in the 60, or was it mph.
