Well it still does not want to let me lean it out. Today when i ran it, I didnt run it that hard aside from full throttle a few times and some laps around my front yard but i leaned it out and noticed that it was giving more power like its supose to, It was still up around 280 tho. When i turn it down and make it more rich it makes the motor almost worthless as far as power is concerned and it it still runs right around 250. Does anybody have any idea what im doing wrong or know why its doing this?
