No 32:1 which I think is 4 ounces per gallon That’s what Swedetech recomends.I’m 16/24 gearing which is 1.50 Maybe I’ll try 25 or 26. I think your right about it being to rich. I ran it today and stepped down to a 182/58. Saturday was the first time I ran it and I really didn’t want to stick it. When I went richer I may not have run enough laps for the plug to read. It was a little warmer and more humid today but not by much. Today I was low 47’s on Mojo D3’s Low 46,s on Hoosier 60A’s. I try to run the D3’s over there because that track eats tires.
