Doing diagnostics and getting some facts is always better than just guessing and throwing parts at a problem. Instead of the speculation, how about just putting a vacuum gauge on it and seeing if you do or don't have a vacuum leak. If not, then you can use the same setup to adjust the idle mixture screws on the carburetor.

Then put a timing light on it and check the ignition timing, adjust if needed, and with the light still attached you can test to see if the centrifugal and vacuum ignition advance systems are functioning. Then reevaluate the performance with a road test and we can go further from there.
