it doesn't take much... it's a bit of trial and error. Too little and you get the same issue.. too much and you don't close the circuit and cause the gun to fire.

Go a little bit at a time... it's very little.. we're talking fractions of 1 mm here.


Be super careful when taking the gears out, make sure you keep track of the shims on the gear axles and make sure they stay where they're supposed to go. Unless you feel like reshimming them... which is never a bad idea since it's all open anyways. Look up shimming from the bevel technique.

You can test the tightness of the shuttle by using a screw driver to emulate what the cutoff lever does. If it takes almost no effort to flip the shuttle up and free of the prongs, you're on the right track. You want it be loose enough that the cutoff requires little force to trip it, but tight enough that it all connects to complete the circuit.
