I just rotated mine to the next 4 holes so I didn't have to cut any of the casing away. I did have to raise my motor mount, which took some time with cutting and welding. I'm pretty sure your idea would be quicker, though.

I may be out of date but a torque converter is more like a fluid coupling. This is more like THE CONSTANTLY VARIABLE TRANSMISSION (CVT), it changes it's shape to achieve different speeds. This transmission is used in some Mazda vehicles, I just don't understand how the term Torque Converter was applied to this. Little things that get me lol.

Sometimes if there is no load on the engine (like the wheels are up off the ground then it can do exactly what is shown in the videos but as soon as you put it on the ground then yes the pull will free spin until the rpms get higher. Yes sometimes the belt will spin as well but it will not have the force to engage the driven pulley. You can test it out by rolling the kart over to tree or something stationary. Try starting there, that will stop it from taking off in the event of it engaging while just at idle.

Blackhorse Racing makes the only decent inexpensive ones. I have a 40 that never skips a beat and just got a 30 series from them also. These things need to be perfectly staight and have the belt on the correct way.
