I would bet that the changes you note are simply a matter of the
transformer being just a bit small to match perfectly with the
capacitor value. Typically when the xfmr is bit small things run
pretty smooth if the gap is kept closed down. If the gap is
opened up then the coil starts to run a little rough and eratic.
