V-One S Racer
It may not be your idle screw that has the problem in it, it could be your low speed needle not being set right.
If you try adjusting your low speed it should help drop the revs a bit, i think if you richen it will lower the revs a bit, try that.
you may when richening have to open the idle up a bit higher if they get low enough.
But as long as the car is not moving when idling, is there a problem? you have less chance of stalling when sitting on the grid.
where is your low speed currently set at? (Aprox mills from the turny thing, i cant think at the moment of its name) (*I said mills cause each time we mention how many turns from close we get in truble of "Almighty Squiz" ^^^Just kidden Squiz^^^*)
But yeah, i run in turns my self on low speed.
