the overflow was not connected - just an open hole in the cistern.

The overflow not being connected wouldnt have contributed to your
problem..
I thought you said it only flushed when the water was dangerously high
but now you have bent the float arm to raise the level.????

I didn't explain myself well.
There is no overflow attached to the cistern,
leaving a hole in the side of the cistern where the overflow should be.
I sealed this hole, allowing the water to rise higher.
