automatic choke problem

greetings from Turkey

the engine stays above 2000 rpm after the start and unfortunately the cycle does not fall
why it can be welded

sorry for my bad english

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

work properly yes

Here is a link to a Pictorial and explanation of how to adjust the idle rpm. Just be sure that you only turn the phillips head idle adjustment screw. The two brass colored straight slot screws on either side of the idle adjustment screw are the Air Mixture Screws for the fuel injection throttle body. Do not turn those brass colored straight slot screws.

Possible ?? sticking throttle cable.

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

it only lasts long in cold weather

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.
