Hi. With some lenses, the easiest way of fixing the sticky aperture is to apply some 99% isopropanol to the blades (using a cotton bud or similar) and then manually use the lever to open and close. Repeat a few times and the isopropanol SHOULD remove any grease, oil, etc... and evaporate cleanly away. It's worked for me with a couple of Pentacon lenses - so maybe will work with Chinon here?
