Carb info overload

This is pertaining to my 1955 860. I was having an issue with my original tsx593 carb leaking and found the bottom of it cracked around the bolt in the bottom of the bowl. It was beyond fixing, so I was able to get ahold of the bottom of a tsx706 lower to use in place. I wanted to get another 593 as a backup so I ordered one from an Ag website. The one I received from them was a tsx976... definitely not a 593. When I called them they said according to their "parts book" it should work. I've always had the understanding that for that tractor only a 593 or 706 would work. The 976 doesnt have the load adjustment screw/needle. Can anyone positively tell me it will or wont work? They are willing to take it back, but only store credit. I wouldn't have bought it if they would have said I wasnt getting what I wanted. The info on these carbs is either overwhelming or sometimes underwhelming depending on what I'm looking for. Thanks for any info

Lotsa carbs for the 172 will work besides the tsx593 and tsx706
which were the originals. The tsx 976, from searching on the
Internet, seems to be for a Ford 172 industrial engine D3JL-E which
decodes to a date of 1973. Did you check the fuel inlet size,
chances are it's bigger than your tsx593. Do the throttle and choke
connection locations match? Personally if I ordered a tsx593 and
received something else I would return it. Chances are it would
work or could be made to work though.
 
It seemed to bolt up just fine, I just couldn't absolutely verify it was for a 172 vs a 134 cu in engine. I tried to find the info online, but it was vague. I was only really concerned with the fact that it didn't have both adjustments, so I couldn't be sure it would work as it should. Just not enough experience personally to say one way or the other. Figured I would ask and learn here.
