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
