The day that I flew it was a lil cooler outside, maybe 15 degrees in temperature difference.

Yes when I tuned it, it was with the cowl of. But I have a very large exit whole at the bottom off the cowling.

I dont have one whole gallon through it yet, almost though.

I think if I retune its gonna be ok, I mean this engine is still breaking in. It wasnt out off tune real bad, but it was. I was gonna try and tune it and fly it this weekend, but they are calling for some bad weather over here for the weekend. But im definately happy with the power off the motor, man that thing is a power house running rough!!! I know I alreay said that, but im just shocked with the performance. I dont have two small holes in the cowl for tuning the engine, I have to take it of to adjust the needles. Maybe I should drill two holes that way I can use a long screw driver to adjust while the cowl is still on. Good idea are not?
