Not really, just use your ears.  Set it so that you hear it actuate (click!)
just as the throttle plate comes off its stop then make sure you hear it reset
(another click!) as the throttle closes.  Tug on the throttle cable to
simulate the normal opening of the throttle plate; grabbing the throttle plate shaft
and twisting it can induce a bit of an error in the switch setpoint because
the slop in the fit of the throttle plate shaft to a worn throttle body can
allow the throttle to rotate about a slightly displaced axis of rotation.
