Hey guys, I’m hoping someone can maybe offer me a nudge in the right direction. I have a 1966 Norton N15CS and I am the second owner. The original owner installed concentric carbs on it. I just got the bike running at work and decided to ride it home over the weekend and it began fouling the plugs on both cylinder. So I thought I should double check my float height. I checked both carbs and the fuel level on both carbs is level the boss for the float bowl mounting screw closest the the engine. I am checking float height with the carbs installed on the bike. That boss measures .170” from the surface of the bowl which I think is the lean side of the spec. I have adjusted my pilot air screws from a half turn out to 2 turns out. They are happiest around 1-1.5 turns out but regardless of where I put them after about 2 minutes if idling the plugs are black again. Is there something I am missing? Should I lower the float height some more? I would really appreciate any suggests anyone may have. Thanks in advance
Dennis
