Deere used a Zenith carburetor on 3020 and 4020 sometimes. I have a collection of service bulletins and one says if you can't tune the Marvel Schebler, replace it with a Zenith. The die cast M-S  used a vacuum diaphragm to operate the acceleration pump and that diaphragm tends to fail and not be included in the carb repair kit. Shoup http://www.shoupparts.com sells Zenith carbs for 3020 and 4020, and likely many other tractor parts places. They weren't cheap at Shoup the last time I looked. My gas 4020 has a Zenith carb.

Zenith carb from a 190 is different than a 190XT. Neither one will bolt on to a Deere 3020 and work as they are configured.
