Need help on removing dual carbs, ‘95 SPX

I got a free, what I believe is a SPX ski that according to the vin is a 94, but on here I saw a few that mentioned if it has the sponsons it’s a 95.
Anyway it’s fugly as hell, I call it the circus ski. The motor is solid, compression is 155 per cylinder, but the carbs are in desperate need of a rebuild.
Looking at the carbs, I don’t see how I’m supposed to get a wrench in on the nuts holding the carbs on. How am I supposed to get to the nuts to get the carbs off? I was thinking maybe a crowsfoot wrench might work?
I didn’t see in the service manual on how to do it, just tells me about rebuilding the carbs.

Any and all help is greatly appreciated.


Background on this ski. I got it from a production company here in Hollywood where they used it as a prop in some movie. They sprayed painted it, but luckily they didn’t mess with anything else. I have my hands full on this one if I decide to restore it and sand it all down and re-gelcoat it a new 2 tone color.
Here’s a picture of it in all of its yellow, teal, orange, purple, reddish, ugliness.

Last two digits of the VIN will be the model year.
The engine tag will have the engine size.
Yes it is a 94 for sure according to the VIN. What made things confusing is some people on here and other forums said if it has sponsons it’s a 95, but I’ve also seen 94’s with sponsons.

Where would the engine tag be located on the engine?
 
See if there’s a tag on the magneto housing
Thank you.

As for as removing the carbs, do I need to remove the rotary valve cover just to get the carbs off? Seems like extra work and big chances on F'ing up the timing.
In the shop manual it only says, "Twin Carburetor Models Only. Remove screws and lock washers retaining carburetors. Remove carburetors from intake manifold."
As of now I have yet to take off the carb screen (housing arrestor) to get a better look, but just in case it only see the nuts on the manifold, how can I get these carbs off?

???

What motor is this? I’ve never worked on a 657 or 587, only 717’d and 787’s. No need to remove rotary valve cover on the 717 or 787 but if you need to remove it, it won’t cause you any timing issues unless you remove the actual valve, but removing the cover won’t cause it to go out of time.
 
Thank you for the comments. I looked around on Google today and found a few random posts that said Rotax recommends to take off the rotary valve cover to remove the nuts on the carbs to get them off of manifold. It gives a bit extra room to swing a wrench.

But first I’m going to try my luck with my crowsfoot wrench to see if that will work. I’m not sure it will work, it’ll probably be slow going, but worth a try.

Motor is 649 (650)

Post a few pics of the steps to get them off
 
I’ll probably start working on it in the next few weeks and I’ll take some pictures then.

From my reading, on the cover there’s 4 bolts: 2 on the top and 2 on the bottom and the bottom ones can be a pain to get off.

Because I can’t see this being the best way I went out and took some pictures of the carbs and noticed on the manifold 2 Allen head bolts (maybe a 3rd) which I’m assuming are holding the manifold on. I’m not sure if this will also remove the oil pump though?
I’m thinking these might remove the manifold and the carbs without needing to remove the rotary valve cover. Not the easiest to get to, but looks easier.

I also could see at one time these carbs were removed and whoever did it, removed the cover by the looks of the paint rubbed off of the nuts on the cover.

Any thoughts?
