It started right up cold that time and idled great for 15 minutes. I shut it down and restarted it fine. The next few times it acted like 1-2 cylinders were loading up and ran very rough with popping in the carb and exhaust. It eventually goes away and idles fine and sounds great. Last time it did that cold and took 3-5 minutes, dripped some gas out of the carb and then the sound completely changed and ideled great. Seems like points would not get better, Could it be as simple as idle mixture is way off? It is a new cap and rotor. Car is in cool basement/garage in upstate ny.

Sounds like your cap and rotor is junk. Try swapping it out with a good used one
