Carb Identification

[Orange]

Would like to get some information on identifying
MS Carbs for WD45, D17, 170,175 Allis Chalmers
Tractors that have no tags or markings. Are there
any bore measurements or identifying features on these carbs.

Thanks
Orange

The carb them self should have a tag most of the time on the back side that has a number like this.
TSX464 or TSX561 or TSX773 all of those are number for a carb on a D-17 late or a WD45 with a choke cable
