i was trying to start my rustler today with the 2.5 and it started but only when i held the ez start button down, as soon as i let go, it dies. it alsao sounds like it is idling high, but the idle screw doesnt seem to be working. help would be appreciated

try changing the plug
then set the needles back to factory settings and go from there

i actually did, and i did 4 turns out, i also ran nitro cleaner through the engine. there is tons of smoke. it still dies when i let go of the button
