Under the carbs there is a little black screw turn this by hand anti clockwise until 1-1500 revs if this doesnt work the choke may not be going all the way off or pilot screws under float bowls in recess been adjusted too far screw gently all the way in DO NOT over tighten then unscrew approx 1.5 turns out on both carbs if your experiencing flooding from carbs the bowls need to be removed and the pilot jet attached to the float needs replacing hope this helps steve
