Carbon problem in the carburetar of honda aviator?

hi, i have honda aviator 2 years old i must the say that the scooter is very much confortable and work well in all the conditions. The average is overall cool and didn't give you much maintenance cost to give. The problem with my scooter is it gives starting problem mechanic told me carburetar need to get changed what to do. Is he right?

I think the mechanic is rights carbon do come in the carburetor and it just need to get clear no need of change.
