64 Slant carburetor problems

Kind of strange, but yesterday, my car stalled out 4 different times waiting at stop signs. So, I sprayed the carburetor with wd-40, adjusted the air fuel mixture, changed the fuel filter, and sprayed the carburetor with some gunk carb cleaner. Took the car out for another drive, and it stalled 2 more times. So, I parked the car, and decided to look into a rebuild. This morning, I started the car up and drove it for about an hour, and no problems at all. Perhaps, my cleaning fixed the problem, for now!
