Also the carburetor heat controll lever labeld as "AIR INTAKE SHUTTER" (Don't really know how it suppose to work on this airplane)]

That's exactly what you would expect, the warmer air entering the cylinder is harder to compress, so less power and lower temperatures are expected.
Many car engines use diverted air warmed by the cooling fins or radiator to provide warmer air for the carb. I suspect that's happening here.
