Hello,

For some reason my boat is set at around 1300-1400rpm at idle. I am trying to adjust the idle screws on either side and the main idle screw but if i drop it down below 1200 or so it will die. Is there a simple fix for this or anything i can do i am not sure if the carburetor needs a new carb kit and to be cleaned or if I am just missing something.
