Welcome to the forum. Most gummed up carbs just need a thorough cleaning, new float valve, O-rings for the air/fuel and carb drain screws, and a bowl gasket. If the diaphragm is torn or the acceleration pump brittle, there are aftermarket replacements available on ebay. Ultrasonic cleaner or seven day soak in Berryman Chem Dip will usually get a carb clean.
