No second shot

[Harry Collins]

Bill,

I'm new to single triggers. My cousin gave me her fathers Parkers and one of them has a Miller single trigger. I paid big bucks to have it work and it still fires both barrels most of the time when the left barrel is selected. One thing I was told is that most old single trigger problems relate to tension on the tang screws. I was at a friends house this past weekend and was handed an AYA that would not fire the left barrel. I could see the rear tang screw was not indexed. I took it home and indexed that screw and tighteden the top tang screw one full turn. It would fire the right barrel but not the left. Backed off the top tang screw one half turn and proceeded to run a half a box of shells through the gun without a hickup. I hope you find the problem.
