| Is your engine idling smoothly? Does it skip or hesitate when applying throttle? |

| If the idle adjustment does not help and the cables are not sticking the only other thing I can think of is a possible air (vacuum) leak somewhere. |

Ditto To check for air leak, easiest way is (with engine running) spray injector to cylinder head mounting rubbers with carburetor cleaner & listen for change in engine sound/rev's |

| The 'fast idle unit' is connected to the throttle body and is controlled by the coolant temperature. That's why the scoot must be at full operating temp before adjusting the idle (either via the idle adjustment screw or the air mixture screws as well). So in cold weather it takes longer for the coolant temp to raise and therefore the idle speed will be higher for a longer time.
So as has been said previously, check the air filter then check for a vacuum leak. Then adjust the idle screw after the engine is up to operatinh temperature.
