Finishing my Kibler colonial build.
Took flintlock apart to polish and put back together with the help of this forum. Thanks y'all.
Put rifle together and went to check trigger operation.
Went to half cock, then full cock, fired sparked all good.
Tried again, and would not hold at half or full, nudged single set trigger up a bit and engaged normal.
Seems like after firing the trigger is not returning forward enough just by a hair.
Any ideas?
