You are absolutely correct.
While the HP Gold Cup 40 is a very nice engine, it has nowhere near the power of a more current 40. It also is not designed to be overloaded with a large prop. That does not work well.
Here's a pic of my Kadet MK2 with an HP 40 Gold Cup with many hours on it previous to use in the Kadet. Prop was a Master Airscrew 10-6. Take offs were very long. In flight performance was very good. Landings were not fast or long.
