Ok I solved it, I have determined that the reproduction carb is a piece of junk and should be scrapped for aluminum. I had an original zenith carb sitting around that I thought was bad, I had it in the corner of my workbench, and birds had been pooping on it, I put that carb on didn’t even clean it, and it fired right up and I drove it around, it was responsive and didn’t smoke. So the moral of the story is don’t install garbage on these great tractors.

Instead of scrapping the repro, send it to me. I’ll use it.

Hmmm.
I'll have to try putting bird poop on a carb next time. L.o.l..

Congrats on the diagnosis though!
