Those integral crankshaft/rod setups will have needle bearings instead of the usual slipper-type insert bearings. More likely than not, the reason the rod bent was the needle bearing tried to seize up on the crank. Even if you do happen to get it straight, I'm betting the engine won't last more than a few minutes. I think I'd be more interested in adapting an engine to whatever the toy it powers that has a better repair parts source.
