Parabola,
Unfortunately, having had experience with this type of scope, I can see the type of mounts use do not adjust easily. The easiest solution would be to change to Redfield type or similar mounts with adjustments built into the rear mounts. Failing this, you can resort to filing the dovetails to move the scope in the desired direction. To move the point of impact to the left, move the rear of the scope to the left, or the front of the scope to the right. If necessary, you can move both front and rear of the scope. The rifle was made without having been drilled and tapped for mounting screws and it may have been drilled improperly. It is also possible to move the bases by opening the hole(s) in one or both of them and shimming one side. It is often surprising how little the scope has to be moved to sight it in.
