Joe hit it close...
To elaborate...you can push the clutch lever with your hands. It is stiff, prop a thumb on it and give it a good shove...the arm will move.
These engines are manufactured, and assembled, well before the end user gets the product. The clutch pressure plate will become stuck to the clutch friction material.
Remove the right side cover, (release the clutch), and tap the pressure plate ensuring that it is floating free from the friction material.
There is a lightweight spring behind the pressure plate...
