hi, im using novarossi .12 with slide carb.
when i start those up for the first time, the wheels want to get stand.
after a few minutes. the wheels get run in idle position.
when i turn down the idle screw till the lowest position before the engine get off, the wheels keep running.
anyone know how to set it up?
i already see the tutorial engine tunning on youtube, and it must turn down the idle screw, but nothing happened even on the low rpm.

thanks for your help guys.

Have you checked your clutch? Sounds like the clutch is kicking in too early. Could be the clutch bearings if it is, they have a habit of locking up when the engine gets very hot

i guess so... i just checked the clutch, and yesS! thats the problem come from.
now its running great...
cheers....
