I just got a boat with a 35 HP Johnson and I can get the boat to run with the throttle cranked up but when it comes to idle the motor dies. It sounds like it's running out of fuel. I adjusted the idle mixture more to rich and it doesn't seem to help. I have also replaced all of the fuel lines in the motor. Is there any thing I missed? Does anyone know what the proper setting are on the Carb? Thanks for your help. Jeremy
