Hi I own a manco dingo kart and untill recently it was extremely slow, about 15mph. I decided to adjust the 5hp briggs and strattons governor to increase the top rpm because it seemed to be only reaching perhaps 1500rpm. I loosened the arm and turned the governor screw anticlockwise untill it reached the more like 30mph which is what it should be capable of. The problem is the kart wont idle without engaging the clutch. The idle speed is too high and the kart moves as soon as the engine starts. I adjusted both the idle setting down to no effect as the throttle plate is half open. The clutch definately doesnt need adjusting. Any help is appreciated thanks!
