When I first discovered the springs were bad I decided to replace them. Well,,, it didn't take long to figure out the levers were bad as well. When setting the trap the off-side ( these were not fourcoiled ) of the spring lever would go down way too easily. I don't know how to explain it any better. The spring side obviously has more pressure on it so it came up first. You would push down on them and they would bend rather than go down. There's an off chance that maybe my brother still has one of those traps. If I can find one of them,,,,, I'll put this topic to rest.
