sounds like the engine speed governor is sticky
try unbolting the gas tank, remove it, and do a thorough lube and clean of the governor lever at the top of the engine
also there is a very fine lite weight long spring connected parallel to the governor linkage to the carb throttle, that will cause "hunting" (speed variation) if the springs breaks
Inspected and lubed the linkage. It's free and not binding. Still, the problem persists. It's more of a slight misfire than a surging.

You might try disconnecting the low oil shutdown circuit. Mine failed.
One easy thing to check. I had the same symptoms - surging when the choke if fully opened, ran fine with the choke at the 1/2 position. I removed and cleaned the carb and reinstalled everything and the problem remained. While double checking everything I found that I had reversed the gasket between the filter carburetor, covering up some holes. Flipped the gasket around and it ran fine again.
You might double check that all gaskets are in the correct orientation.
