The air screws and pilot jets effect idle to 1/4 throttle, the needles meter 1/4 to 3/4 throttle and the main jet effects 3/4 to full throttle.

 

Loose the CT needles. Try the stockers. I have the exact setup as you. Solved my issue.

i moved the needle to the 3rd notch on the CT needles, and it is good from idle to 1/2or3/4 some where in that area i will try my main jet to see what that does. if that dont work i will go with the stock needles, with the stock needles were did you put the clip? thanks

 

Just the stock position. 4th I think....
