Are my mixture screws toast?

Yamaha 30DEO 2 stroke from 2000s, runs but I was never happy with idle. Today I pulled all 3 mixture screws, top and bottom have flat end, middle one is pointy. What I am thinking:

  1. It should be like that (unlikely)

  2. Top and bottom were sometimes overtightened in the past by previous owner, and the pointy end snapped.

  3. Middle screw was replaced by incorrect screw.

What I've found, originals are super hard to find and quite expensive, are aftermarket parts available?
