I'm thinking I'll just use this thread for a place to mark down stuff as I fix it.
Radio - Got one of the original radios working. Found a bunch of wires shoved up under the dash that look like someone was using a tape player or something in the car. Front speaker was blown. I replaced it. Rear speakers were unwired. I rewired them. So far I've found a dozen talk radio stations and radio Disney, not optimal, but good enough. While I was in there, I replaced my rightmost dash light since it was out.
Carburetor - Since it will be cold soon I finally got around to installing a high idle cam. (I think that is what it's called? It's what the high idle screw sits on.) So now it goes through its idle steps nicely. Overall the choke still comes off too quick, but I'm debating whether to try and actually fix that or just unplug the electric heater and forget about until it's warm again.
Timing - I grabbed the timing light and it was at about a degree BTDC to right on TDC. I advanced it on the lowest idle until it was just below where I could still see the timing mark before it disappeared behind the water pump. It idles way better and seems to have a bit more power all the way up. I haven't yet had it on the highway, but so far I haven't heard any knocking.
Still lots to do, but those needed done before the cold really kicks in. I get my license Wednesday.
