Briggs and Stratton over revving

Briggs and Stratton over revving model 125k02-0389-e1. It’s over revving, can’t seem to find the problem. I have changed the carb out. Also the governor spring and air vane spring. I have moved the governor back and forth that does nothing. I can choke it up with the air vane spring.
