Mower running rich? Never settles into smooth operation

We were given a cheap push mower when my wife and I moved into our house. It didn't run, and supposedly only ran a handful of times before dying. I decided to get a Honda and see if my brother and I could get it running so he could have it as a backup mower at his house.

So far he has:

replaced and gapped the spark plug
re set the spacing on the ignition coil
replaced the diaphragm/gasket on the carb
replaced the air filter
ran a couple tanks of fuel through it to clear of old gas


It's a 098902-1110 b1 motor

Any ideas?
