I have an old set of Thompsons, the only problem I seem to have is its very hard to set the flag off, the trippers seem to stick, so far Ihhaven't found a way to fix it.
We have many thompsons and a couple moosheads and LOVE them.You might have a burr on the piece that holds the ring, try filing that piece down a bit.
Or cut it back a little bit with some dikes. I cut all of mine back just a touch so the are a little touchy for trout fishing. Love thompsons great traps.
Love my Thompson traps! I've noticed that they have a couple of different springs on them, some are wide and stiff, some are thin and trip easier, I got rid of a bunch of traps this fall, keep the ones with the thin springs.
