Can anyone tell me what exactly I'm looking for? It's a xtreme 90cc 2 stroke, bought it second hand. I put on a new carb (ad said it was a pz19j). I'd like to rebuild the old one, maybe add a one size up from stock jet and other mods.

You didn't say what the old carb was....if it's the same as the one you bought, maybe they will sell you a rebuild kit and jets. Do you know that it needs to be up-jetted? How many sizes? What other mods are you planning on that carb? It's not a racing carb.
Good luck.

Changing jet sizes without the engine being modified in some way, will make the engine run like a sewing machine on sleeping pills.
Use the jets that came in the original carburetor.
