I replaced the spark plug and air filter. I also cleaned out the carburetor. It will start now (which is an improvement), but it stutters fiercely and dies when I try it on grass. https://www.youtube.com/watch?v=343gn1ujrv0

You didn't get the carburetor clean.
Can you describe how you cleaned the carburetor?
Sorry, I didn't see the youtube link. Sounds to me like it's running RICH. If you can find the fuel adjustment screw, turn it in a half turn and restart. Then turn the screw in slowly until the engine rpm picks up. How many turns did you open this screw when you put the carb back together?
