Vacum Advance plate wobble

Maybe the breaker plate is worn or the bushings? I have seen this a lot on rebuilt units, after the vac advance is applied it cocks the plate instead of turning it.

Have them look at it again, there is a spec that on points or electronic the dwell again IE air gap should change no more that +- 1-2 degrees max. This will affect the timing a lot it it tilts..
