Answer I believe you have a dirty carb, but the source is before the carb. I suggest you clean your fuel tank, fuel lines and yes the carb one more time. Lets make sure you have clean and proper fuel flow to the engine.
IF you still have a problem, I would be looking at doing a valve job. IT sounds like the valves are not sealing properly. Pay particular attention to the intake valve at this point. Perhaps a simple lapping of the valves is all that is necessary.
