You’ll wanna check how the flywheel spins in your hand with only one set screw…if you see too much wobble, you’ll need the second screw to true things up,….sometimes you can get away with one set screw, sometimes you can’t……the purpose of the second screw is for setting it to spin true….too far out of alignment, and the magnet could bang into the sensor, or get too far away for a proper reading…..again, you can observe this simply by spinning it by hand and watching for the flywheel and magnet to run as true as can be….
