I'm running a 190 main jet with the lid off, sparks filter kit and jet kit. I have the sparks cam on the way and will keep the jetting the same. I turned my air/fuel mixture screw about 2 1/2 to 3 turns out from all the way in. The air/fuel mixture screw is on the bottom of the carb, facing straight down. Its towards the front of the carb. To get to it just loosen the clamps holding the carb in place in the front and rear on the intake boots and tilt it sideways. Pilot clip? You must mean the pilot jet you don't have to mess with it, that's what the air/fuel mixture screw is for.
Your jetting is based on how much air you are taking in, when you remove the lid you take in more air giving you a lean condition, that's why you have to go with a bigger jet. Jetting is also based on altitude, temperture, and the humidity.
