If you have not done so, do a full tuneup - points, cap, rotor, plugs and wires and then set the timing. Check for vacuum leaks and maybe do a compression test as well. Use a good fuel system cleaner like Seafoam while you are at it.

Also check the fuel pressure, it should be 6 to 8 lbs.

A new fuel and air filter are always a good idea when doing a tuneup.
