I have a nitrostar 15 ss in my t-maxx
just broken in, maybe 10 - 13 tanks total. I've always seemed to have this idle problem.
the car idles too high, where the clutch engages....way too high.
if I turn the idle screw down anymore, it stalls.
Is it the low mixture screw?
what else could it be?

Thanks,
Gabriel

Try the pinch test on the fuel line to see if it is to lean on the low side pinch the fuel line and it should run for about 2-4 seconds before it dies if it runs longer it is to rich
