New stock CL350, just rejetted by mechanic. No power under 3k RPM. Stumped...

I should mention that the throttle plate isn't what's limiting motion here. The idle adjustment screw, when completely backed off allows the plate to shut against the carb body. My issue is that the screw doesn't go far enough in to open the plate wide enough at idle. It compresses the spring fully, which then limits the width between throttle plate and carb body (~1mm tops).

Okay, I've got pictures. Let me know what you guys think. In the pictures below I'm maxed out, the compressed spring is limiting any further adjustment to open the idle position. I'd prefer to be in the middle of a range over maxing out one side of it.

Would love some insight. Cutting/Swapping the spring is okay or a nono?

Okay, and those pics have the carb oriented float bowl side down, correct?
Also, any suggestions on where to get new screws for the spindle? The current ones are pretty stripped. I noticed that the screws have small holes in the ends (to squeeze with pliers). Can't find them in the parts diagrams though.

So, as I'm visualizing this, I'm definitely realizing that the motion of rotation has to be in the wrong direction. I don't see any other configuration where this would work.
Are you guys 100% sure the plates are installed improperly (other than the fact they aren't centered)? Because at full throttle they are open at a perfect 90 degrees, and the beveling lines up. If I were to flip the plates, as recommended, I would have to turn the plates in the opposite direction, which means that my idle adjustment would no longer be the thing limiting movement at idle. Seems to make more sense to me as is, but if you guys are saying it's wrong, I believe you.
I'm just babbling, so I'll try to figure something out when I get home tonight.

Split personality, I fake being smart
I think the throttle plates are installed correct direction but not centered.
As for screws, you don't have special tool to stake them so don't worry about that. I open throttle plate then use a large linesman pliers to burr the end, the screw head doesn't get badly squished as it's (relatively) much larger surface area

Throttle plate centering directions: (correct me if I'm wrong)
Loosen screws
wiggle spindle/plate
eventually, I'll be able to seat the plate at the top and bottom, at which point I tighten the screws
burr the ends of the screws to keep them from backing out
sound good?

Okay, I got them centered. One of the plates was oriented incorrectly (bevels in opposite direction).
New diaphragms came in, weren't that hard to replace. They look good and seem to seal very well.
Idle adjustment remains the same. Maxing it out, I can't get the thinnest 'carb cleaning wire' under there, which is much much thinner than a paperclip. When I shove it under there and look, it looks like I have 2-3 full rotations needed in order to stop at that point.
