hi i got a nitro rc car for xmas and i have done everything to it accept set the idle switch and i need to do that because when i run it when i stop the engine stalls/cuts out and i looked through the manual at how to set the idle but it wasn't very clear on what i had to do
the car iv got is a 1/10th scale bug crusher and the idle is underneath the air filter and its a little black screw but im not sure on how to set it or what i have to do to set like do i have to have the engine running or doesnt it matter wether its running or not
