This is trial & error but worth the effort, Wind all three PRIMARY MIRROR screws forward as far as they go. Now wind the screws all the way back counting the turns untill the screws stop.
Now screw them up again but only half as many turns, This puts you at 50% level and it may be right at this point. Now collimate & see a star to confirm. If still out try going up or down in 2 turns at a time or till you discover which direction is improving.
It's a pain but well worth the time to correct.
