    03 yamaha 150hp 2S, rebuild, first start, carb leak

    runs good for about 15 seconds, then gas starts pouring out of the front of the middle carb and it stalls out. Stuck float?

    I am not sure if this video will help on carb rebuild for a 03 150 yamaha.

    Information
    CV Performance | Common Carburetor Fuel Leaks (cv-performance.com)

    Did you rebuild the carbs with all new parts?
