This isn't as much of a problem when the engine is cold because the tolerances are looser. When the engine is hot though the tolerances tighten up and the flow of current is barely able to overcome the frictional forces.
Like I said - a bigger battery solved my problem and I needed a new battery anyway. In your case I do believe that fixing this crimp will solve your problem.

Perhaps, but I would still check the primary leads for voltage drop when warm. Internal wire resistance rises with temperature, resulting in excessive voltage drop and you get hard starting.
