Help identify these 3 parts

Please help me identify the location of these 3 items. I just finished rebuilding these Mikuni BN46 carbs and I can't figure out where they belong.

They don't go to the high, low, or idle screws.

Hhmm,,, the small spring probably goes to the accelerator pump arm,,, those damn things come off and you don’t even know it it, so,,, unless my accelerator pump is not working,, I do not take them apart!
The longer spring looks like a rav valve spring,, which will make thevski run like shit
 
And that small “ o” ring is from the rav valve,
Just carefully remove the other rag valve taking very careful note of the order if the parts.. take lots of pics,,,
Of course the other one could have been installed incorrectly,, you may have to find a diagram in the manual

Thanks for the feedback. Unfortunately, I haven't touched the RAV valves, only the carbs.
I also took a lot of pictures and video and scoured through every frame trying find these items. I've also searched multiple diagrams.
 
After cleaning out the hull, I found more unidentified parts

This ski was recently purchased and needed carb work. The entire hull was full of oil and lots of garbage. The picture that I posted today shows the items I pulled from the rear of the hull. Two matching springs, two matching teflon washers, and one larger spring.
Unfortunately, this is my first ski and so I have zero experience and I'm unable to find these items in the manual.

Is your ski working?

Yes, it runs.
After rebuilding the carbs, replacing the tanks, and hoses, it started right up.

BUT, in another post(in this forum), I appear to have a rod knock. Which is extremely bizarre because the knock goes away when the exhaust pipe is removed.
