  • Help with carb cleaning

    I have a 2003 yamaha 130hp txrb. I'm planning on cleaning my carbs because my engine isn't running right. I haven't cleaned since i bought the boat. I have a few questions on a few things. I have a service manual but not the best. In the diagram for the carbs i can't find the jets that need to be set. I know you have to count how many times the screw rotates but i don't know which screw that needs to be seated correctly. Can someone show me which screw it please thanks. I have never done this before but I would like to learn. Thanks guys i appricate it.

    its dirt simple.
    only screws that need adjusting are the pilot air screws.
    7/8 of a turn out from lightly seated.
    floats set at about .63" with the gasket in place.
    the rest,just make sure its clean.

      Ok awesome, I'm going to get at it today. Is it best to use a ultrasonic cleaner ,just spray carb cleaner or leave it in a small bucket full of carb cleaner?
