Have noticed that the clutch pedal on our 1965 minor does not fully return to the released position ie level with the brake pedal. If I reach down and give it a pull it does come up by about 1.5ins and level with the brake. Crawled underneath (took 15 mins to crawl out again )

and checked the pedal return spring which looked in good order so cannot figure out why we have this free play movement.
Not having any issues with operation of clutch just like to solve problem?
All suggestions gratefully received.
