I have an SC 25 engine and the engine does not cut out when I close the throttle on the carb compleatly. It is a brand new engine the carb stop has been moved so the carb now closes compleatly. No matter what I do with the engine it will not stop or cut from the transmitter. It will just idle very slowly I don't know where the engine is getting air from and it is anoying because the engine will keep running.
