    that carb is 57 years old and previous owner surely  ran that engine without  headaches.

    The structure of the carb did not  change  and remains a bunch of passages and ” holes” to  let fuel sucked in

    did you  try to install it on the other JW you got the  “working” carb from

    Although I know you cleaned it   did you run some  small mono or “carb brushes”  in all  passages.

    Some folks have been known to plug up the air intake to the carb …..thinking the lead pellet  had dropped out !

    compare your good  ” needle” carb with the jw22 … &  check parts diagram ..

    aside from the hs  jet and cover bolt   look for any  missing or ” extra parts”  !  did you open up the air silencer  and clean out any  bugs

    p.s. … could not remove left jpg. 🙁
