I've spent way too many hours trying to fix this damn torsion spring, but I've replaced every single part of the mower chute door assembly and there is absolutely no torsion whatsoever. When I turn the mower on, the door flops open instead of staying shut. I know it has something to do with the torsion spring, but if one end of the spring goes thru the hole on the chute door, where does the other side of the spring need to sit? I've attached a few pics for reference.
