Surely someone has the correct floating screen for that tractor. I would call Wendell Everett 740-922-3335 or Welters 417-498-6496.
Or you can replace the screen that was on there. Wendell Everett sent me one for my Z back in the "90s.
A good used part would work. That said, One of those late 206 engines was the only one the oil pump would not prime on its own when I rebuilt it. I had to force some oil into the pump through the oil gauge line port to get ti to prime.
