Thanks! I think I understand how you would fix it. I took a look to my broken lens that sit on my desk. I saw the holes in the lever base underneath the screws. Aren't they too short for adjusting lever position? I think they are just about 3mm long. The screws size are about 1mm though.
Also, this might be silly questions, what brand of the set of screwdrivers should I have? Where can I get them? And what size should I buy?
I tried to take a part a broken lens with the "general jewelers screwdriver set" but they were too soft. The tiny screwdrivers tip were just damaged. And the screws just still sat there! lol.
You're only moving the lever enough for a half stop. I don't think it needs to move a lot.
I just got these: "JIS Type S Driver Set, Pollicis 4Pc by Moody Tools" through Amazon, sold by MicroTools. If you pull those up on Amazon, they'll also show you sets from Hozan, which I also got (version 2). The Hozan set is mostly for larger screws. The smallest size (labeled 00) will work OK but lenses often have smaller screws which concentrate too much pressure on the 00 size and ruin it. The Moody set has a 000 size. In the US, these drivers seem to always use Phillips designations for sizes, and it's really annoying sorting out whether the seller is trying to pawn off a Phillips or not.

1 more question.
How about the FA, or F lens that have the aperture ring. The question is if I adjust the lever position, then can I still change the aperture manually via aperture ring correctly? Won't the size of diaphragm be wrong when I change aperture?
Once you move off the A position and use the aperture ring's settings, the lens uses a separate mechanism to set the aperture blades. The camera relies on the lens to get that right and just shoves the lever fully up in M mode.
