Watched the video, a few comments:
1. your carb does not look rebuilt. It must be clean as new, there should be no leaks, no fuel stains on it, etc. I would recommend taking it off, and re-sealing all gaskets with some Permatex #2. If you have not already done so, check the float level and the operation of the accelerator pump too.
2. test the engine with a vacuum gauge
3. does your breather pipe smoke when the outside temp is warm as well? Does it start smoking right after a cold start? That could be a huge blow-by, which could also indicate why your oil pressure gets a bit low at times. My 201 shows a steady gauge regardless of the engine speed.
4. check dwell and ignition timing, also, it was already mentioned bout the points spring incorrectly installed...
5. please fix all your gauges
6. the radio would need new caps
7. nice houses in your area!
Later:
8. you need to troubleshoot that chirping noise, that is concerning. Take the plugs out, disconnect the coil, and spin the engine to check if it's there...
