I might be able to help if you describe the kind of "carb problems" you are having. Leaking fuel? Running too lean? Idles rough? Etc...

from what your describing sound like a float issue to me but if a couple of different carbs have been installed on there and nothing was found (dirt,ect) that would make the floats stick up and continue to let gas in i would be puzzled, glad to hear dealer is trying to fix for ya.

the bottom of carb there is a skrew and a hose, that is a drain and the skrew should be closed so if anything you would be flooding out the machine before any gas would come out that hose.

Since the carb has been totally replaced on two occasions, do you think that there is a sending issue between the tank and the carb itself? Are you building excess pressure? Just a thought...

This is a little puzzling, You say 2 different carbs? Are they using 2 new complete carbs or are they re-using some of your old carb parts? i.e. float bowl or anything.
If it is coming out of the overflow tube ( with 2 or 3 different carbs) I'd have to say that your gas tank is building up pressure like saskabush mentioned, possibly just from engine heat, hense, the 20 minutes or so. Take the gas tank vent line off and blow thru the line, cant blow thru it? then thats your problem. Next thing to try, take a small drill bit and make sure the gas tank vent nipple is completely open, drill it slightly larger than before.(keep gas tank cap on for this, you dont need any sparks near an open gas tank) Gas tanks are blow molded plastic and maybe they forgot to drill it completely from the factory or theres a little extra piece of plastic on the inside of your tank plugging the vent line. Your tank is mounted above the engine so its gravity fed, no fuel pump to worry about so the only way to build up pressure is to have a non-working vent.
If its coming out of the float bowl drain tube, (located at the bottom of the float bowl) I'd say its it the casting of the float bowl itself (and thats only if they re-used your float bowl on the new carbs) to fix that, just plug the end of the plastic tube w/ a screw. Hope this helps ya and you dont have to sell it..........tigger

One other thing to check, do you have enough clearence between your carb and exhaust header? (an inch at least) A hot pipe too close to a carb will boil gas out the overflow. I doubt thats your problem, but it happened on my 05 500.........tigger

Good call on the "re-built" carb. I just took it as being a *total* replacement. If you start with bad things, you will usually get bad results.

If the carb is in good shape, I would bet you dollars to donuts that you have a pressure issue. All in all, the gas tank and carb are pretty simple assemblies, I am sure that you will get it worked out soon.

Start with the simple solutions and work towards the complex...

Tigger beat me to the punch. If they are reusing the floats and such from the old carb, that could be the issue (cracked float which is taking on fuel, and thusly flooding the carb). If they are using all new parts, then I would check the other things Tigger pointed out. Venting...ya need it. Might even just be plugged with mud or something.

That is normal for any atv carb with an overflow. The rougher the trail, the more it will drip.

Dont plug the overflow! That will flood the engine!

Im telling you, They are supposed to drip a little when riding, or at least its normal. They are supposed to have a hose on them routed to the ground, and most people never notice the fuel running out of them.

I work on these things for a living!

I agree, do not plug the overflow tube. It's also a vent for the carb.
If the quad run's fine, why mess with it? A little drip here and there wont hurt it at all. Unless it's a big drip. Give us a little more to go on with your problem and we should be able to help ya...................tigger

I also have the same problem on my 2005 400i. I called the dealer and he told me to either bring it to him or try cleaning the carb myself. I removed the carb and took it all apart...that's when I noticed this black grit-like stuff that was in the area where the rubber pointed float thing pushes up into to shut the gas off...it's attached to the white plastic float things (2 of them) that push the rubber shutoff up when the bowl is full. The grit must have been clogging the shutoff and allowed the gas to freely flow out when I stopped. I cleaned it all out good with STP carb cleaner and then used compressed air to blow everything clean. I then installed an in-line Purolator 1/4" fuel silter and it's been much better....although I do occassionally get a couple of drips here and there.
