I can control it with the throttle rod, it self regulates after running a few seconds.
Need to know cause and remedy.

Make sure the throttle shaft in the carb isn't sticky which can delay throttle/governor response. Also could be a sticky governor, but not as likely.

Sounds like the governor spring is missing.
