The 2 things I look at first are fuel and spark. Since this car is pretty old, I would look to make sure the fuel pump is providing enough gas to the carb. If so, then buy a rebuild kit for the 2 barrel which is pretty simple if you have any mechanical abilities. I would also look at the distributor, points, and condenser. If they haven't been changed in awhile, just buy new along with a new distributor cap, rotor and while you are at it you might as well get some new spark plugs and wires. Those are the simple things to do. If this motor has a lot of miles on it, maybe the cylinder compression is low. If this is the case you probably would have noticed a decrease in power and it would use oil or even show signs of smoke out the exhaust. It could be lots of things, but start with the simple and inexpensive things first. Good luck.

Yes, I would check the choke, and the timing as well. You can loosen and turn the distributor just a bit if you lack a timing light.

Pump the gas pedal a few times the prime engine of your choke isn't hooked up might have to do that a couple times and it should fire right up
