If you have a rubber fuel line somewhere between the fuel pump and carburetor here is what to do.More than likely you probably have a piece of dirt between the needle and seat.1. Pinch off the rubber hose needle nose vice grips 2.Start the car and let it run for about 30 seconds 3.After it has ran for 30 secs release the vise grips. The built up pressure in the line will usually blow out the dirt. Works for me
