    sounds like the blow test is fine  and it should close up when full

    could the pump be at fault  for some reason. …

    since it is all self contained (pump-carb)  try to  take off the carb and do your testing on the bench.   …ventilate the place !!!

    check the float for snagging on the edges  when assembled and filling with fuel…even if the blow test works fine.   check float… .flotation

     

    check float drop

     

    got the book ??  section  4b pages 265 and up covers that carb.
