The problem you're describing would have nothing to do with the carburetor, if it is clean.
The engine would only need starter fluid to run, if the top end was worn out and in need of a rebuild (cylinder, piston & rings).
The screw that isn't touching the throttle, is the idle "mixture" screw.
Turning it between 1/2 - 2 1/2 turns is addiquit to run the engine.
That screw is to fine tune the idle speed.
Once the engine is reved past idle, it has no effect.

Scooter Carburetor Problems

The needle valve could be clogged with something.
Or it is set too lean (motor will die) or too rich (motor will run irregularly, maybe die and the exhaust smells like a lot of gasoline).
The one screw at the throttle is probably the 'idle' setting.
Then some carbs have a 'low revs' and 'high revs' needle.
Or the fuel filter is clogged, if you have one.
Could be something else too.
Next time please explain a little more clear, like, using interpunction (commas, periods etc.)
Good luck
