the best way is to go up about 115-120 on the main so it 4 stokes badly, then work down until it runs clean and id stick with that, your atomiser seems rather large as well, my set up on a tv175, standard apart from 24mm phbl and sito clubman through a baffleless airbox but with filter is 100 main, aq 264, d22 3rd notch needle, 48 pilot and 60 choke, the last 2 are too big but i can work round them and like it running cool on over run
