Your condenser could be junk (even if brand new - most are). If you put a new one on, put the old one back on and see what happens. Make sure your vacuum advance is functioning.
Check for vacuum leaks around the carburetor and manifold and both ends of the windshield wiper vacuum hose by spraying choke cleaner around those areas while it's running. If the RPM changes, you have a leak in that spot. Use a bottle of propane gas to do the same thing.
Look down the throat of the carb while its idling and see if fuel is dribbling off the center venturi. Fl;oat level could be too high flooding the engine.
