I bought a pair of hornets but one is basically unresponsive and like ~1mm wider than the other. I’ve taken them apart, looked at all of the parts individually, made sure I was setting it up correctly, and yet still when I screw the halves together it just doesn’t become narrow enough. Any help is welcome and appreciated. Tia!
