I turned the needle 1 hour anti clockwise (my 3 hour position in the previous post) and the car is still fast but slightly sluggish. When I had turned the needle 4 hours I still had a good amount of smoke and cool temps. All that worried me was that slight hesitation. When I was driving it on full throttle, there was no sign of hesitation besides when I give it full gas on the start. So it the hesitation could be a lean sign? Even though I have smoke and all that?
