This hand is completely read dependent. If villain is a nit or loose passive (that is, limping here with weak hands when he should be raising), KJo is a snap-fold. If villain has any sort of clue, KJo is a good call.
In spots with minimal/no FE like this, just calculate your pot odds as if villain open shoved. You're risking 2,724 chips to win 3,499, or 1.3:1 odds. You need to think you'll win at least 43% of the time to correctly push.
