car wont idol stationary
got kind of a strange question. i am running a rb ws7 in my losi 2.0 and it has been running fine. i fired it up today same as usual, and for some reason it wont idol correctly. the idol rpms are fine (not idling real high) but when i stop the tires keep spinning on the box and putting it on the ground the car rolls kinda slow. and when i engage the breaks, the is a strange humming sound like air is leaking. but if it is just an air leak i dont understand why this would make the car want to go. i tired turing down the idol and that is not the problem because when i engage the breaks and hold them it just wants to die. would really appreciate the help
