There are actually two different topics here.
Carburetors very rarely "wear out".
Finding competent service for them is difficult at best.
On several occasions, I have purchased carburetors that were very good knock-off of a Walbro LMB that is used on many old Onans and lots of Kohler small engines. A Kohler in yard service can wear out the throttle shaft and bearing areas. I have repaired this several times and then pick up a knock-off. Often these need minor modification that I don't recommend.
What many refer to as a rebuild is nothing more than a complete cleaning. The Walbros with a rubber pointed needle often give problems when the rubber point is damaged by current motorfuels. But if that is the problem, a kit is usually the simple solution. Past that, if you did not tear the gaskets, all you really have to do is soak the parts in a good solvent and the clean the passages with a tag wire and blow them all clear.
