Hi
Bit of throttle wont move the car as its running too rich and loaded with fuel.
If the wheels were spinning as you said before, when the idle was high, it means clutch is good.
Rev the engine a few times slowly to clear the fuel from the engine, then it should move.
Alternatively, if its too...
Just decrease the idle with the idle screw. 1mm idle gap is just too big. Try that and report back.
And make sure LSN is at factory setting (read manual).
Cheers
