Looking for advice on repair

[Coach]

Go back to your local gunsmith and see if he has any parts "left over" following his work. An easy piece to leave out which would account for the gun not cocking is the cocking slide - #13 on the parts list you can view by going to the home page of this site and selecting Technical Information from the menu on the left.

And it would be easy to tell if the cocking slide was left out because when you opened the action, the lever would not stay to the right, since the trip/pin/spring slide into the little dimple on the cocking slide and without pressure from the cocking slide the three parts would just be dropped down into the action.
