What is in his range that I would beat? The only thing I could see is AKs pushing his flush draw. Everything else I have to be behind right. What is a 4bet range of an unknown here? JJ+ AK+ or maybe just KK+? I am getting 2:1 on the call, but does he show up with a flush draw enough to justify the call? I can't imagine someone that just sat down is playing any low pairs or AJ this way.

Is pushing preflop +EV here? Seems to me at best I am a coinflip and more often then not I am probably behind. He 4bet so I imagine he is not going anywhere.
