Thanks all for the replies.
I don't know what flicker points are (I'll look that up shortly) but the new points and condenser arrived over the weekend. Looks pretty standard. The carb-to-manifold gasket is back ordered, as is the top carb gasket, so I'm in a holding pattern until they arrive - target end of this week or early next week.
If the cleaning, air pressure and points/condenser don't fix it then I'll look into the ultrasonic cleaning for the carb. We just got back from our last trip for the season so it's not an urgent repair at this point. I'd like to get it done before it gets too much colder, though. It's a nice option to have when the house power goes out.
