pull the bowl off the carb, clean the debris out of it. There is a small hole directly in the center of the bowl area on the carb (where it pulls the gas into the carb from the bowl) this gets gummed up and clogged. Take a small wire and run it up and down that small hole to clean it out then put back together. Add some seafoam to the gas to clean out the gasoline gum in the carb. Hole this helps. Stan
