Welcome to the forum!
I wouldn't want to just (effectively) trash the machine, at least not without some investigating.
Will the engine move if not using the recoil starter? With the spark plug removed (so you aren't fighting compression), you could keep the handle squeezed (use a zip-tie, etc), and then see if you can rotate the paddles in either direction, by-hand. At a minimum, pull the spark plug wire, for safety. Not quite sure what you mean by "freeing up the shaft with some shaking."
If you broke a connecting rod, I'd expect you should be able to rotate the engine at least a little bit in one direction or the other. If it's completely seized, of course, it wouldn't want to move at all. Presumably it was running with proper oil-mixed gas? Sometimes people have freed up engines using a big wrench on the crankshaft, and working it back and forth, after adding something like penetrating oil to the cylinder.
They use the same R-Tek engine as the 2450, I believe, just set to a higher RPM. My 221 also uses the same one. So there could be a chance at getting a cheap machine as an engine-donor. The 221 is the successor to the 3650, I really like mine, I wouldn't want to just give it up.
