Simple stuff, is there a fuel filter inside the carb? Most Rochesters had them there and you'd have to take the fuel line off the carb to get it out. It may be partially plugged. Check your cap and rotor. At least take the cap off and wipe everything off inside. This time of year moisture can build up inside the cap. Check your timing, but know that the distributor could simply be worn out. The gear that connects to the cam was notorious for wearing out. I believe the aftermarket still sells a brass replacement distributor gear. If you have fuel, then the only other thing is spark. If you have a volt/ohm meter, check the resistance on the plug wires. Remove the plugs and see what is going on there. That would also be a good time to do a compression test and see if there are any internal engine problems.
