Zenith TU4-C Carb Help

Hello all,
What thread size is the idle jet 5F7640 which is screwed into the carb body and extents into the ideal circuit in the float body. I thought it was a 1/4-28, but that doesn’t seem to be thread. I am trying to clean up the threads in the carb body where the jet screws into. 
Thanks in advance.👍👍🇺🇸🇺🇸
