You'll wanna switch to smaller main and air jets, but I can't remember exactly which ones. I think I had a 145 main when mine was smogged. I don't remember where the air bleed screw was either, but you will wanna adjust it accordingly too. Best bet is probably to contact weber directly and see what the 32/36 dgav comes with stock. You'll know when you got it right, it will stumble, cough and sputter and be gutless, but will pass. Good luck, Nate
