Yeah, it does appear to drive well.
Do you think I've maybe rotated the tps on its locating screws the wrong way.
ie; i've turned it clockwise to feel the point of spring tension, then backed it off a touch to nip it down (This is exactly how I did it)
When I should have been turning it to it's anti-clockwise limit, backing it off a touch, and nipping it down in this position?
Wouldn't be so bad if I could adjust it in situ, but I have no chance getting my sausage fingers in there with anything useful for undoing and doing up the screws.
