1979 Pontiac Firebird Formula

The car is in piss poor shape right now. I bought it from an idiot that was just destroying the car. I've had it for a few months now and i'm doing my best to get it back in running shape. when i got it, it was running horribly. I Drove it back to the shop with some of the weakest brakes i've ever felt. I'm running short on cash so i'm rebuilding what i can now. Now it's not running for some reason. I believe the carb is in need of rebuilding, so that's my next project
