    Carb info needed

    I bought a rebuilt Yamaha 175 2 stroke outboard last year. I need some info on the carbs. the numbers on them is 64000, s, 621400, D21, P, 77010. I don't think these are the original carbs. The title says the motor is a 2000. Can anybody give me more info so I can adjust these carbs?

    2000 175 carb setting

    I have a 2000 Yamaha 175 2 stroke that was rebuilt last year. The motor started losing rpm at mid throttle. I replaced the spark plugs and they were all black and wet. Is this motor running too rich? If so, how do I adjust the carbs to lean it. Thanks
