Use of carb heat on the approach is not a one size fits all. The POH does not say to apply carb heat in the approach.
Landing: "Carburetor heat should not be applied unless there is an indication of carburetor icing, since the use of carburetor heat causes a reduction in power which may be critical in case of a go-around. Full throttle operation with heat on is likely to cause detonation."
Very different air intake design to the Cessna.
Also the prop would be turning even if there was no power, unless the engine had siezed,
