Rex rs450 carburetor broken?

Hey, after numerous problems with my carburetor, I bought a new one and now I have the following problems: When I accelerate while the scooter is on the center stand, it slowly accelerates on its own until I turn off the engine, even though the throttle cable isn't stuck and it's completely in its original position, both on the carburetor and the handle. The second problem is that the scooter is running really strangely. When I'm at a traffic light, it's very quiet and almost about to stall. When I accelerate, the scooter stutters for a few seconds at around 4 km/h and then accelerates to full throttle.

Was the carburetor cleaned with the nozzles and new seals were used?

If it was installed from the cardboard, it was needed and was not disassembled before, an overhaul could help.

Since your vehicle is a so-called “light pressure carburetor”, you will have to adjust it perfectly for your motor, but this is not as easy as a cable-driven slide / or flap carburetor.

To How To Do You will find plenty of instructions on the web .

The carburetor should be as here And this is functionally a constant pressure gasifier.
