A picture would really help and we can't see any of your albums. From your description, I'm not sure you understand how limit screws work. The low limit only sets the location of the cage over the small chainring with no tension on the cable. In other words, it stops the cage from moving toward the seat tube. This should be set before attaching the cable. The high limit screw only stops the cage from moving too far past the large chainring, in order to prevent throwing the chain off the outside of the chainring. There should be no reason to remove it.
