Barn Find: ’91 Fourtrax 250X – Rough Idle

I just purchased a ’91 Fourtrax 250X in 100% original, very good shape.

It’s idling kinda rough though, once warm it chokes and shuts down, and I have to start it with the throttle wide open, otherwise it doesn’t start.

Does this look like an easy fix like cleaning with carb spray or Seafoaming it? Or does this look like a more complicated fix? I know a tune up is in order, just need to know what to focus on.
