Hey guys I need a little help here. I'm buying a 1983 nissan 280 zx and the car runs for about a block or 2 and then stalls out because it's running to rich. am I getting myself into quite a bit here or is this sounding like a easy fix. I know I can't get a straight up answer but just looking for some helpful tips and advice. thanks!

Welcome and congrats.
There are a lot of things that could make it run rich.
Air flow meter, fuel pressure regulator, head temp sensor, stuck/leaky injectors and more.
Start with checking the fuel pressure.
Good luck.
