Welcome back old friend. Your rubber diaphragm located just under the carb top/cap has a pin hole (or worse) hole in it. Easy fix, can do it your self. The spring will pop out, don't lose it. Then run a few cans of carb cleaner through it. My 07 had set for about 2 years when I bought it. Started, but would not idle. Idle jet was clogged. After running it through a few tanks of gas with cleaners, it cleared right up. Good luck, and make sure you put spring and needle back in correctly. A slight smear of grease on outer edge of diaphragm will keep it in side recessed area of carb that the rubber lip go's down inside of top of carb. Do this so you can put cap back on without worrying about crimping the rubber if it pops out of carb top when putting cap back on.
