That is after you take the gears out, modify them and put them back in, they should rotate continuously.

ok,i see
well,let's see if i have unterstood  ;) :
i open up the servo,
i take off the largest gear to find the potentiometer
i bring back the others gears(if i've moved them)
i plug in the signal for 0 rotation
i should see them moving continuously
i rotate the pot head till they stop moving
i superglue the pot
i remove the plastic peace from the large gear
i put back the large gear
and this is it


have i missed something?

You don't have to put the gears back on, just turn the pot until you hear the motor stop moving. Also, the motor should have a teeny gear that doesn't come off, so you can look at that.

You need to be pretty accurate with the pot, try adjusting it with a pair of tweezers, you should see the gears slowing as you get near the right point.
