Pedersoli PA long Rifle trigger change

[barracudadave67]

Hi All
I don't like double set triggers, so I changed mine to a single trigger on my Pedersoli PA Long Rifle.I got all the parts from TOW. I had to lengthen the trigger plate. I tig welded some extra metal on the front and back of the plate.
I used TOWs Isaac Haines trigger, and trigger plate. Parts cost $21.00 plus shipping. Had to drill a swivel pin hole in the plate.
I had to fit the trigger for the correct pull, and posistion in the trigger space. Then I removed the fly on the tumbler, cause it made the let off to light. It turned out good. Trig pull is 4lbs, now.
Im happy with it.
Here's a couple pics, sorry I didn't get any of the welded plate.

How did the fly make the trigger too light?

The fly would not let the sear go into the full cock notch on the tumbler fully. If I just barely touched the trigger at full cock with the new trigger , it would go off. So I removed the fly. It works without the fly, and it has a 4-5 lbs trigger pull checked with my gage.
