are you saying you're using the throttle trim to set the idle stop?
if so, you need to set it on the carb itself, not the radio
what kind of truck is it?

Chewwie, it's almost impossible to diagnose an egine problem on the internet but if I'm understanding you right, the truck rolls when it is at idle. If this is happening then it is one of three problems.
1 bad clutch bearings
2 a weak or broken clutch spring
3 a sticking clutch shoe ( this happens alot with alluminum shoes. just take them off and file a slight 45* angle on the outsides of the shoe. hope this helps.

sounds to me like the idle speed screw is set too low and you have compensated for this with your radio trim (+) which makes your idle ok, but when you brake it pushes that slider back past your idle spot to where the needle is set (too small an idle opening) and it dies. you need to set your trim back to zero and turn that needle in until it idles. when you brake it shouldnt close that idle gap.

yeah what he said...
if you are certain that is good, check the clutch
if the clutch is good, then its prolly the engine tune

So , today i pulled out the motor from my hpi firestorm and took off the clutch bell , guess what the freakin clutch spring broke !!! what does that do anyways, i know it holds the clutch shoes. does it make the truck stall or cant hold idle ?
#12
yeah a broken clutch shoe will make it stall and not idle
