How about the rest of the fuel system? Have you removed, drained, cleaned, the tank? Have the rubber fuel lines been replaced with a tygon type? Ethanol blended fuel will destroy rubber lines from the inside out.....the exterior may look fine, while the inside is being eaten up, causing problems further along the fuel system.
After everything is clean.....you might think about using something like Marvel Mystery Oil on a regular basis. I add .4 ounces (4/10ths of an ounce) at every fuel up. Last year this cost me $1.98 to treat the 35.4 gallons of fuel I used to go 3,159 miles. Scooter is just over 4 years old, and has just over 9,200 miles on it, never have had a starting or running problem....and I have never cleaned the carb.
