I'm in the crowd that says ignition is 99% of the problem when something doesn't run right, but it's important to get the wheat and chaff sorted. Look around carefully for vacuum leaks. Look everywhere. Plug off nonessential vacuum lines and see what helps. Spray around the carburetor with carb cleaner or even WD-40 to see if the idle changes. If the thing has good acceleration when cold, it's because the choke is covering up a vacuum leak, a lot of times, and not the timing or points. That is, ONLY if it changes when the choke is open. Points and timing will affect a cold engine in pretty much the same way as a warm engine.
