6. Idle Stop Screw and Throttle Arm

The idle stop screw limits the travel of the carburettor barrel. By adjusting the screw (turn the screw in to open, out to close), the barrel‘s ability to close will be limited. The opening in the barrel controls how slow the engine idles. When the barrel closes completely, the engine will stop running. For most applications, it is advised to adjust the screw so that the barrel will close completely. The radio can then be setup to control the carburettor barrel closure via the throttle arm.
