How to remove, rebuild, and reinstall the carburetors on a 1992 Sea Doo XP. This is the rebuild kit I used for my particular engine: https://www.jetskiplus.com/new-seadoo-dual-mikuni-carburetor-rebuild-kit-needle-seat-base-gasket-xp-580-587 But do some research and figure out exactly what you need for your year and model. To get the vacuum/air pump used in this video to test pop off pressure: https://amzn.com/B0002SQYUA This video is for entertainment purposes only. 50sKid assumes no liability for any repairs or modifications performed by the viewer as a result of the information contained in this video.

And to do this you do not need to pull the rotary valve cover just the carburetors
Shannon Williams (3 days ago)
Also you have to know your accurate pop off pressure settings from the book and as long as they were Within five PSI of each other it really doesn't matter
Shannon Williams (3 days ago)
And this carburetor setup has a small cable that runs your oil pump you always want to check your oil pump alignment with a mirror it has two tick marks that must be lined up at idle speed if you get this wrong it will burn your motor up or it will foul your plugs
Shannon Williams (3 days ago)
And also when you're setting your jets those settings can vary a quarter of a turn so if they were way off it has to be put in the water and tested because the manufacturer even says that the settings can vary a quarter of a turn on your high and your low speed Jets just because it runs good on the trailer doesn't mean it will in the water

You forgot one important step always do a fuel pressure check on your fuel system if you have a bad tank valve or missing gas cap gasket it will fry your front piston by creating a lean condition because these do not have fuel pumps they have pressure diaphragm pumps

All you need is a short wrench it shouldn't take you more than 10 minutes to remove these

Several of these vid's illustrate testing the 'pop off pressure' but nobody explains how the carb regulates its internal fuel level. I understand why they don't use a conventional float and bowl as the attitude of the watercraft will not be constant. Exactly how does the carb know it needs fuel admitted to it?
50sKid (2 months ago)
These carbs have an internal fuel pump that uses the engine vacuum.
Russ G (2 months ago)
Do all these carbs have an integral fuel pump, or do some systems use a remote pump? My Tigershark with Suzuki 900 triple has a fuel pump that runs off crankcase vacuum.

Looks tricky. I just ordered a carb kit for a 650

Great video.Very helpful thankyou.

Thanks so much for the video! I was nervous about doing this, but not anymore. One question. It appears I have two fuel lines going to carb, but I'm assuming one is a return line. I want to put a filter in line on fuel hose, so would that be the top hose? Thanks again!

Thanks for the vid. Is soooo helpful. Iv got my carbs off my 92 xp, the same as you have there. I have found needle and seat are 1.5 and you say 2.0 is what it needs. Is this the same for mine? I cant find anywhere on the internet for the specs of what it should be. Cheers

Great Video SR I got my kits from here https://www.ebay.com/itm/SeaDoo-Dual-Mikuni-Carburetor-Rebuild-Kit-Needle-Seat-Base-Gasket-GTX-1992-1993/292352753351?hash=item441194fec7:g:-5gAAOSweZJaINlR:sc:ShippingMethodStandard!32137!US!-1&vxp=mtr

Great video man ... I have a 2000 sea doo challenger and I'm going to do the carbs .. I was wondering where u got your parts at? And also did ur not came with the Needles Or did you purchase them separately ..around how much should I expect on each kit ...thanks for the help
50sKid (1 year ago)
I probably bought mine on eBay though.
50sKid (1 year ago)
I dunno, the quality varies on eBay
Edgar Barbosa (1 year ago)
50sKid ..what are your thoughts about getting the parts on eBay...found it for @30 and in another website found it for $45
50sKid (1 year ago)
I don't remember where I bought the parts but yes I did have to buy the needles separate

I CAN NOT THANK YOU ENOUGH!!! your video helped me get my 95SPX back up from the dead
Night Speed (1 year ago)
50sKid at 29 30 I installed the little small plastic tabs on the opposite sides not the actual one-way valve itself but the small black inserts will this make a difference

+Night Speed sweet! Enjoy it

Stephen Joyce (1 year ago)
Thank you for this great video.  Very well done.  I decided to tackle the rebuild on a 94 XP.  Little different setup but the rebuild was same.  YouTube is such a great educational tool with videos like yours!
50sKid (1 year ago)
Glad it helped you out!

Thank you so much for the great quality and description on how to remove that crazy carbonation system off. It ran perfectly so far.

I pulled off my carb and my valve plate full off how can i find out what position to replace it 1992 ski doo xp dual carb
Harley Strine (1 year ago)
You need a timing wheel to put it back on correctly. SBT sells them cheap. It's called a Rotary Valve timing tool.

quick question my pop off psi is between 36 to 60 psi thats a big margin any recommendations?
Joshua Kahn (1 year ago)
Great video, really clear and informative, thanks! I'm looking at getting a 97 GTX that might need carb rebuild, I assume it's basically the same process.
50sKid (1 year ago)
Pretty much, as long as it's a 2 stroke carb engine

my bad is a sea-doo GTX 1993
marlon gaitan (1 year ago)
hello,,,thanks for the video, very informative,,,i have a 1991 GTXsea-doo with the same dual carburetor as yours but my is not starting,,,if I put starter fluid by the filter then it will start but then go off after the fluid is gone,i install a fuel filter on the fuel line and I can see that there is not fuel getting suck into the line.Any comment,,can you help me out...thanks.
50sKid (1 year ago)
Either the carb needs to be rebuilt (there is a fuel pump built into the carb) or there is something wrong with the fuel switch unit that is preventing fuel flow.
Fstarocka Burns (1 year ago)
hi thanks for the vid - just pulled my single from a 92 seadoo sp - I have a question. The pulse plate, as i took it off from the outside - (is this correct? the plastic gasket goes directly onto first oring and metal?). I got 2 identical gaskets here which is why im asking). outer plate paper gasket plastic film sandwich plate (with large oring) rubber gasket that blocks the big round ring but is open at the fuel filter and a side ring carb base (with fuel filter etc) When I reassembled the plate and applied 5psi to pulse tube, i got bubbles leaking out between the plastic film and paper gasket next to it - no scratches to the aluminum seal lip, etc. Does the plastic film pulse back and forth? I ordered the cheap set and used mostly original parts as they were still good, my diaphragm had a pin hole in it. Fyi my pop off is at 29psi - right in the ball park. Also - when i do the suck/blow test on inlet/out - the inlet has a noticeable difference (in = easier obviously), but the out seems to have the same resistance in or out - what could case this? I didnt change the plastic washers - not sure if the original kit was better quality. The diaphragm that came out had the pink original mikuni pin - so using as little from kit as possible. thanks!
Fstarocka Burns (1 year ago)
50sKid hi thanks yes I verified it on the manual. mine kept leaking past plastic and gasket even at 3 psi so skinned lightly with permatex ultra , all good now. I read the pulse cover can warp, probably what happened. well my pop off is perfect too. will pressure test fuel tank to see if it's leaking. thanks again!
50sKid (1 year ago)
Your single should be identical to the one I showed in the video that had the pump diaphragm in it (I don't remember the order from memory, so I would suggest just referring to the video)
Abbas Saleh (2 years ago)
thanks for the video. I got a question though. My seadoo runs good for like two minutes then it starts boggin and I can only run it on idle speed. Do you have any idea what it could've been? is it related to the carbs. thanks.
50sKid (2 years ago)
Might be a fuel delivery issue. Check for clogged fuel lines, bad fuel sending unit, that sort of thing.
colby harris (2 years ago)
I love the video but what do I do if I'm not getting pop of pressure the vacume pump lines go flat around 22psi.
Roger Hockemier (1 year ago)
Bending the arm down or up which way increases and decreases you never said in your video or on the reply to this guy
colby harris (2 years ago)
Ok I have a 1992 seadoo xp I'm saying it when up to 22psi and never popd off.
50sKid (2 years ago)
If 22psi is not within spec for your model, you bend the little "arm" that lifts up the needle valve. Push it down on the spring side first, which would lift the needle up, then bend the arm that lifts the needle up or down to increase or decrease pressure. don't push down on the needle side and bend the spring side because putting pressure on the needle can damage its rubber tip.

This vid is perfect! Gotta wait for the impact driver to get here to finish, but I'm not mechanically inclined and this walked me through it great! Thanks man
Keith Turpin (2 years ago)
This video was so helpful...Thanks.One question concerning the valve plate. If it comes off stuck to, ( I think the flywheel) does I need to go back on the same way it come off? Is there a timing issue?          Thanks Keith

Fixing a chuck on a elect d rill
Keith Turpin (2 years ago)
Yes. I see the mark. #1 piston TDC and it lines up with a mark that someone put on... WOW... how easy was that!!! Thanks again!
50sKid (2 years ago)
Yes it needs to go back on the same way. The nice thing about this engine is it has a timing mark on it (it's a little arrow or notch on the case). You put piston 1 at top dead center and then put the valve plate on aligned with the mark. There are some videos on YouTube on how to use a degree wheel to set timing on a seadoo. Check those out to see how it's done.
tom giambarberee (2 years ago)
Hi awsome vid , just wondering if you know how to bypass the oil feed I want to premix myself . I don't want a fail and my engine to freeze up ... Thanks Tom
50sKid (2 years ago)
Hi Tom, I would imagine you can just drain the oil then cut and plug off the two oil feed lines going to the pump. However, I would encourage you not to do that. The oil pumps on this engine are extremely reliable and don't have a history of failure.
