Alrighty folks, watched that educational (and hilarious) video by Taryl and checked my thermostat, air vane, and spring. All working correctly, and choke plate is closed when cold. And there is no obstruction in the fuel line and fuel is getting to the carb because when I disconnect the bowl from the carb, it is full. Still no dice. What's next?
Still starts then stops after doing many common repairs

You need to see if runs normally for 5-10 secs. Try spraying fuel into carb throat after a helper pulls cord. A shot every 1-2 secs to keep it going. If it runs normally, you still have a fuel delivery problem. fuel may be in bowl but it's not traveling thru main jet to the combustion chamber.
Do you have a primer bulb? You can keep pushing it to test engine run.
If your "run" is more of a burp - you may have a sheared flywheel key = out of timing.

From everything you posted I’m thinking you need to look at the original carb. First take a look at the float on the old carb. When you tip the carb upside down does the float stay level with the carb body or does it go up from the pin side to other side? If it is not level the float seat has swelled and the engine will run lean and be hard starting. Then check the new carb for same results. You may have gotten a bad carb.
Definitely more of a burp. Thanks for the suggestion. I'll inspect the flywheel key.
Thanks, will check this out.
Well folks, I appreciate all the help. Engine is running just fine again. Turns out this problem may not have even been related to some of the things I was saying. I tried all the suggestions, but when none worked, I ended up just looking at a diagram of the engine and starting to take things apart and clean them. Took the cylinder cover off the front and went to town with a brush around the piston and the valves. Also liberally sprayed Seafoam in places that I could not get at with the brush but I reasonably believed to lead to parts of the intake or combustion chamber. Manually rotated the flywheel, watched the cycle of the piston and the valves opening and closing, and cleaned as much of the surface area as was made available by the movement in the cycle. Turns out one of the valves was sticking a bit. Got it to operate smoothly, put everything back together, and bingo.
Again, thanks for y'alls insight.
