I fixed the same problem on a Troy-Bilt I am running now with a Briggs Intek by replacing the carb with a no name Chinese one I bought off Ebay. The name brand Briggs is probably Chinese too. I understand that some of the carbs on the new motors are hard to impossible to clean and figured it would be easier to just replace it. I'd check out what memtb said about upgrading the carb also if one is available for yours.
You probably already know this but you should be able to find a carb or whatever else by searching the net with the model number of your engine.
