@wilsworkshop Thanks. I was looking and hoping that some of them were similar or had the same bolt pattern. I think I found a rebuild kit that fits but now I realize that the two halfs don't mate to each other. The bottom float end of the claim shell is bent badly, creating this big crack. It's a zenith 12158 I believe on an old 70s maybe mini dozer/trencher. Seems like most of these carbs all bolt up the same.
Just pay attention to the way the throttle shaft comes out of the side of the chineese carbs. There's a cheaper version that was the "wrong side" as mine but looked like it would bolt up. And I had to trim about 1/4" off the throttle shaft so it wouldn't hit the engine block, i think it's a "trim to fit universal" length intentionally. Other then that, it just bolted right up and has been working fine for a year or so of bush hogging.
