New Savage X won’t go idle

[SamBRZ2015]

Hi guys,
I am new to this forum and nitro cars, bought my first nitro car yesterday (savage x 4.6) yesterday and follow every step for engine break-in , but I have and issue and that is , even when I turn the throttle knob on the remote to the very low and leave the throttle at neutral the car still moves and doesn’t stay idle .
Even tried and used trimming the throttle at the lowest possible but still seems the engine works harder than it should and the car moves . Can you please help to figure this out .
Thanks

The carb has an idle screw on it. This is a mechanical stop so that your carb doesn't close all the way and stall the engine when your have your throttle trigger at neutral and brake. When your at neutral on the transmitter, the carb slide should be resting on the idle needle with slight positive pressure from the servo holding it in place. Turn the screw counter clockwise 1/4 turn and see if your idle drops.

This isn't your carb, but it's probably similar:
