Opening valve fully to access reserve often cause debris in the tank to collect on the vertical in-line screen and cause blockage. The first thing is to perform the fuel flow test. Take a coffee can or gas can with funnel and place on ground under the carb. Loosen the fuel line at the carb inlet port with a 7/16” flare nut wrench or equivalent. Gently move off to the side and direct down to funnel. Go to Fuel Sediment Bulb and open the fuel valve two full turns to MAIN. Observe fuel flow is a steady almost pencil thick stream with no hesitation, sputtering, stopping and starting. Flow should fill a pint jar in about two minutes. Alternate method of test is to then shut off fuel valve and reconnect the fuel line to carb. Next, place funnel directly below carb, go to the NPT drain plug on bottom of carb, usually brass so careful not to round off, and remove plug. Again open Fuel Valve 2 Full Turns and observe results. If test fails, you can first try to remove and clean the sediment bulb. You’ll need to drain the tank first. At this point you might want to consider cleaning the tank good as well. Methods vary so research that in the archives. Clean the upright screen being careful not to blow compressed air thru it as it only soldered on, but new ones are glued. Replace the brass fine mesh horizontal screen between bowl halves with a new one and use a new cork gasket. Clean glass bowl well. Reassemble. Test with a gallon or two of gas. If fuel flow fails again, time to remove and rebuild the carb. There are several articles in the HOW-TO’s forum –here is a link, click it.
