On my car the pedal had a… well, not really a hard spot… felt like you “pull a magnet off” resistance… So my guess is that the clutch wasn’t adjusted correctly from the get go! I’m thinking the 2 flat arms connecting to the pedal arm just were not is the correct angle in relation to the leverage of the pedal arm! (Not enough angle)
It is a known problem that those arms wear in and having oblong holes, which may create that problem… You might want to check that as well..
i turned the rod 2 turns in and now it feels even… No “hard” spot in the beginning!
