Carter's slogan for many years was "The ABC's of carburetion- - - -Always Buy Carter!" That's the right carb for your engine, the price is right, and it's an automatic choke model. What's not to like? My father, whose shop in Nashville was a factory-authorized service center for Carter through the 1940's and 50's, used to say "Automatic chokes and automatic transmissions are smarter than all drivers and most mechanics!" He was a very wise man!
