Ok I have 2 identical 8 hp briggs engines on the same old coleman generators. So when they start up and run they should go to full or 3600 rpm. One does and the other over revs. I can play around with the governor spring all day long and nothing. Lots of tension or no tension. I even pulled the carb off and made sure it was put together correctly and clean. It was. Not sure what to do. How does the governor weights inside the engine work? Engine model is 190-432
Thank you
