What carb is this?

[Ger88005]

1992 Sea-Doo XP.
I can't figure out what carb this is. It's got 1 adjuster on the side of the throttle lever and 2 adjusters on the opposite side.
Pictured is the opposite side. If you look closely, one of the adjusters is missing. (There's a spot below the one that's there.)
If I could figure out what carb this is, I could get a replacement.
Please help.

This ski is suppose to have 2 carbs, but it's only got one.

Can’t see very well but are you sure one of the 3 isn’t just the idle screw?

 

[Ger88005]

No, sir, I am not.
Isn't the idle screw next to the throttle cable?

 

[mikidymac]

I only see 3 screws, idle, low speed and high speed. Am I missing something.

Thank you Miki, and thank you bk.
I'm going to rip it out tomorrow and take a good look at it. The beast won't run unless I prime it.
I thought it was a diaphragm issue, so I rebuilt the carb, but it's still acting like it's not getting any fuel.
And ideas?

First did you use genuine Mikuni parts including new needles and seats? Second would be the full strainer or selector sucking air.

Hi,

Take it completely apart and make sure every orifice blows through with carb cleaner/compressed air.

Are you sure you have the "in" and "return" lines hooked up correctly after you rebuilt the carb and not backwards?

Did the ski run before the carb rebuild, or what's the story? Its probably something simple, you don't need to buy a whole new carb.

Did you do a new needle and seat along with the carb kit rebuild?

It was running great till it died in the middle of the lake. It was acting like it couldn't get fuel, so I thought it was the the diaphragm and rebuilt the carb. (Only replaced the diaphragm, cleaned it, and replaced gaskets.)
It's still doing it.
I didn't think of the fuel selector. I'm going to throw her together and try it with the gas tank full.
Thanks, guys.

I always bypass and eliminate every fuel selector on every ski I have owned, and go straight from the reserve line to the carb. Also, Im sure they have been replaced since its a 92' but old fuel lines can blow up a thin layer of rubber internally and can start to clog things too.

Thanks to y'all, I think I got it.
However.
What's the stock settings for a mikuni carb?
