I got the mower started. It seems like the battery was just really flat. I suspect I'll be revisiting the battery situation, but it is ok for now. Now the engine turns over and starts, while only clicking occasionally.
Now the problem is that after mowing for a while, the mower will simply stop running and won't restart for a while. I installed a new ignition coil, so a lack of spark shouldn't be the issue.
I also think the engine is running too rich. On my old Mustang, the carb had a pair of needle valves that controled the fuel/air mix. Does the mower have something similar? I looked and only found an idle setting.
The only other problem I found was that a tube leading from the carb to the front of the mower, near the spark plug, had rotted and cracked. In the spirit of backyard mechanic hacks everywhere, I wrapped it in black tape so I could get on with it. Maybe it is wishful thinking, but the mower seemed better afterwards. I don't know what the tube is for, looks like a vacuum line. It isn't a fuel line.
