    Hello again! I recently got my CNS carb and it is pretty cool. I have a few questions or trouble shooting inquires. For some reason, when riding with the fuel petcock switched to on, the motor looses its acceleration (and slows down) once I hit 30 MPH. The funny thing is, though, if it turn the petcock off, the motor will continue to accelerate to 37 MPH and although it wont go faster, the RPM wont slow down. What is wrong?

    What is the read on your spark plug? (How rich are you running)

    The color is a light brown. Could it be the float? If so, how do I fix it?

    Certainly sounds like the float. I'm don't know much about the float on the CNS carbs though.
