I need to know from other users if mine is normal, when you flip the switch to on after 1/2 second or so the motor spins about 3 or 400 rpms and will not completly stop. Is there an adjustment I need to make or is this the way it is supposed to be, the dc motor and controller Lee sold me on his lathe is instant on when you turn the knob and stops when you turn it counter clockwise. Let me know if yours is the same please.--Leonard
