I have same temps going on rite now and im at 55 pilot 185 main and the needles that came with the carbs cels are too lean for the 39s with your set up.with your elevation try 180 main and go to to the other needles

ok thanks, I didnt think i would need that big of a main. But i was a little worried. It always ran better with the cgl needles anyways....
