Sounds like you have a fuel delivery problem somewhere. As already mentioned check your pump and fuel filter. Once that's ruled out check your jets (idles and mains) to make sure you don't have any trash in them. There are also screens located in the carbs where the fuel lines enter. What kind of pump are you running? Are the float bowls running out of fuel? What size motor and jets do you have? These are the questions that come in my mind. I am running carbs on just about everything I own so I am somewhat familiar with some of the headaches. Let us know what you find cause I am curious. Thanks, Ian
