i always used any brand carb and choke or throttle body cleaner that was in a spray can on the shelf for my car. it works good for the car i normally start the car up let it warm up then spray some in while giving it some gas so it wouldnt die. after about half the can i spray a whole lot in and let it die. I let it sit for 10-15 min and start it back up normally have to crank it while playing with the throttle to get it started. Its normally somewhat trying to get it started then have to give it throttle to get it all out with out dieing. this whole procedure causes a smokey drippy carbon solutin to come out the exhaust. however i dont know if i would recomend this in a sea doo. Im not sure if it would hurt any thing so i would wait til someone can tell you for sure. also remember if running outta the water you probally need to have a hose hooked up to keep it cool. and also if you use a hose you have to turn it off if engine dies or you will waterflood it.

That's a big... NO.
First... all that will do is clean your choke plate. Second... it's a solvent. It will displace oil, and kill it's filming ability. This is very bad on a 2-stroke.
And... as asked above... why???
If the carbs need cleaned... take them off, and do it right.

Yes, the carbs need to be completely disassembled, cleaned, and rebuilt.
The problem is that these are strictly salt-water used, and when I first acquired the ski, half the screws broke in the process of doing the first rebuild. Everything is just corroded and electro-welded together. I am actually surprised the thing runs at all, and more so that it runs as well as it does.
I am aware that if I pull those carbs off...IF I can even GET THEM OFF, they will crumble in my hands and I will have to replace them completely.
There is a stumble off-idle when you accellerate, and I will see if low-speed adjustments will fix it. Most likely too lean.
But a teardown is most likely not feasible.
So, you are RIGHT!!! You don't want to hear about it.:ack:

You may or may not recall that I was given the XP after it sat under a beach house for about 5 years never being used. It had sat through several hurricanes and tropical storms, tied to the trailer and tied to a piling under the house, so each time it flooded, it would just float around under the house with the trailer roped to the bottom of it.
The previous owners seldom, if ever, did any maintenance. Pretty much the kids rode it 2 or 3 times off the beach in the spring, it would quit running, and spend the rest of the summer in the shop. Then one more ride off the beach in the fall, quit running, then sit til next spring, and repeat.
So the carbs are in SEVERE disrepair, and mostly just a mass of white iron oxide corrosion.

I thought this was the Challenger, but yes... I do recall the free XP.
Unfortunatly... spraying it in, while running wont' do anything for you. In an old car, where the venturis may be carboned/gummed up from thousands of miles of use... then spraying it in will clear the venturies, and sometimes unclog the ports, at the point of exit, and give a finer spray. (making it run smoother)
On our engines... the issues are normally from internal plugs. (from sitting over the winter) The only way to clear them is with carb cleaner, and compressed air.
If you look around... you can find a set of used carbs (38sbn) for around $75, and since it was a free ski... I'd say that's a reasonable price to make it run.
I have a second set of carbs for the boat, but they were off a freshwater 97 XP and I don't want to see them get nasty from saltwater use.
They are freshly rebuilt so I put them on the boat, then this year I will rebuild and clean the boat's original pair, and keep them to the side.
But I guess since these were on when Karl used them, and they are salt-water used most of their life, I could slap them on the XP and run the snot out of them...
I would like to completely use the XP set first, before starting to destroy another set.

Maybe start shopping around for some used carbs to repair and make better use of your repair time? I was thinking the same thing about marine carbs versus auto where the cooling system is air cooled rather than the jet pump circuit, risk high heat and lube dissolved = sliding parts being damaged.

The one thing you can possably try is seafoam due it it being a petrolum additive I have put it in my 96 xp and it perked up. I would reccommend getting a small spray bottle and spraying in the carbs but you may want to rebuild the carbs i would start by just checking the carb filter becuase thats were most people have their troubles it get clogged.
