the mixture control in a 47 is only an idle cut off and only works when the throttle is fully shut.

there is an automatic mixture control, (amc), inside the carburettor that does it all for you. it is an aneroid that changes the jet setting as you climb.

please do not lean out any helicopter. you might get a big fright.
