With or without the guidescope, set the counterweight to give an out of balance condition so that the telescope would tend to "fall" to the East of the axis if the locks were not tightened, check the PE in this condition. Sounds like the gears/worm are OK but still may have a slight mis-match which could cause the perceived error. I'd also push the scope east then west and see if the PE reflects the "back pressure" Could be you just need some "pre-load" on the worms.
My 2cents worth.
NB haven't found this problem on a GM8 clone.
