You need to measure the carb body length first. So you can compare if you need a long body or short body style carb. I would go with the pwk quad vent aka air striker myself.
So motor side is 38.5mm inside diameter.
Filter side is appx. 57.3mm inside diameter.
Overall length is 153mm. Widest part is 76mm.
The carb dimensions for the long body and short body. The long body is 91mm in length and the short body is 75mm. The long body is the screw top style. Short body is what you'd find on current yz250's. But they come with tps and power jet you don't need that.
Short body
Long body
I don't think what ever model is above will work. My current carb measurement "C" is only 76mm.

I misunderstood your posting. I see now the wording explains the short body and the diagram pertains to the long body. Thank you! What manufacturer does this info apply to?
Those are for the keihin pwk air striker carbs. The keihin short body is called the short body AG.
The current tmx-x carbs off the 06 -21 yz125 would work also. Or the ones off the current ktm's. But I would go with the pwk myself easier to jet.
Thank you, I appreciate all the info.
