The lever was easy to pull because the cover was loose. You actually weren't disengaging the clutch, you were just moving the cover. So, this may indicate an issue with the clutch itself. I can't say what that might be, you'll just have to take a look at it I guess.
Also, it appears you have an early short arm worm. That's going to give a harder clutch pull no matter what.
