There are actually two different topics here.
Carburetors very rarely "wear out".
Finding competent service for them is difficult at best.

Half of what you say is true. (I'm 69 years old) My dad owned a 66 Mercedes 250S with 2-2 barrel split shaft Zenith carbs. After about 60,000 miles, the throttle shafts wore down creating a vacuum leak and the car would not idle because too much air leaked past the worn throttle shafts causing a lean condition at idle. The only fixes: replace the carbs ($$$$$) Have a machinist bore out the worn shafts, install bushings and "o" rings, . . . problem solved. My dad's "Mercedes Mechanic" would fix the problem by pumping grease into the worn shafts. That would work until I drove the car at over 100mph (heating it up) and the grease would melt. Problem returned. My dad always knew.
