I had a carbon build up. there is a trick to getting ride of it. take a good mist bottle and fill it with water. spray it into your throttle while the motor is hot and running. the water will turn to steam and clean out the carbon build up. You need to watch how much you do because it will sputter and spit. just do a little at a time and go through about 300 ml. then put in some fuel injecter cleaner and go for a drive. the part about bad gas is crap. not very likely. i use the cheapest gas i can find and have never had a problem.
