It occurs at the same point. I've got a bolt going through the pedal up against the quadrant, which can be adjusted. When this is not pushing against the quadrant the pedal feel is consistent without this snap/dip, however the clutch does not disengage so won't go in gear like this. When this is adjusted against the quadrant so the clutch disengages that's when it feels snappy and bounces back.

Will try change the clutch cable, but got a feeling this is just how it will always be. Not sure why it's like that when others have got a much better pedal feel with the same setup.
