OK, primary cause spring was not standard, weaker because of smaller wire diameter, also longer and larger diameter than original. One end is slightly larger diameter than the other. Could be the reason it worked for years then did not. The end that is larger diameter can bind in the hole in the sear. Not sure which side was in first as I did not pay attention when I pulled it out.

In one item I have a probable cause plus a contributor. Will still address the other potential problems and investigate a couple that you all suggested. Brought over my working Mag Light to see if parts can be used to repair my HawkEye bore scope. I will continue to look for other contributing factors till I can not find anymore.

The spring that was pulled is on the left, close to 1/4 inch diameter. The spring from the newly purchased Krag on the right .227 diameter and .570 long. Close enough or should I wait for a new one?
