You are better off to remove/disable the governor if you turn the nut all the way in and its not fast enough, though many carts dont go much faster than that anyway because the engine can't rev higher. Make sure you don't have a bunch of slack in the pedal cable before it opens the carb, but make sure there is enough the carb shuts before the engine turns off (via pedal switch). If you keep the governor on there too tight it will wear out the throttle cable faster with the pressure it makes. Some say they can blow the governor in the trans but rarely seems to happen. The real problem is you need more gearing to go faster, from larger tires or HS gears.
