Ah, figure it out yourself. :luff: :luff:

For all flint locks they get stripped down completely, the lock plate is leveled  with either a file and/or abrasive paper, the sear is honed with MicroMesh, the lock is reassembled and I use TSI-321 to lube all moving parts.  I usually replace the stock coil spring locks with an L&R RPL-05 leaf spring lock - faster, better built, more reliable, more durable.

As to the DST trigger assembly, I've only used the DST sets from L&R, usually a T5, don't know anything about the Davis triggers but I'll bet they're good ones.

I found the diagram and notes I was referring to in the original post.  It was in the Lyman GPR Manual of all places. Ha!   The screw that is not numbered and is located behind the rear trigger needed to be backed off until it didn't touch the Trigger Main Spring when the triggers are not set.  Then tighten screw until it touches the main spring and then slowly continue tightening until the Trigger Main Spring touches the set trigger cam.  I keep tightening it and testing to see if the set trigger locks and the bar doesn't hit the lock sear arm.

It's truly amazing what they put in those user manuals!  Glad you found it; hopefully, the problem is solved!

Yep Kees, it is amazing.  The screw that I had to adjust is not shown.  I found it on another forum 25-30 years ago.  I made my notes in the manual, but forgot about it. Ha!  Getting old is not good. 

Now as to the RE Davis trigger assy.  I bought one and it arrived today.  Maybe I will get it installed into the flinter soon.  I think I am going to like it.

Thanks to all who replied to this.
