Here's a blog post I saw while looking for ways how to clean carb. Just wanted to share this to you guys, it helped me and i hope it will work for you too... http://www.iultrasonic.com/polaris-s...-cleaning.html

If it has a fuel pump the filter is located near the pump as it's headed to the carb. but yes the best thing to do for your fuel system is to add a fuel filter. I personally like the clear ones so i can see if the fuel is flowing ok.

I have no idea if you guys are talking about a trail boss (4-stroke) or the trail blazer (2-stroke). They are completely different carbs and the 4-stroke one is a lot more complex. I believe it has an accelerator pump in it. I had a guy rebuild the 325's carb because it is pretty complex; the needle and seat are what he said stick a lot and you can't fix it, just have to replace. I'ts been about a year now and I have not had a problem with it. The Polaris replacement parts are about $40 for the needle and seat. FYI, he said on the 325, they will run completely differently if you have an air filter on/off and/or the airbox lid on/off. Here is is website; he is local to me here in Dallas. PolarisATVrepair.com | Local ATV Full Service, Engine Rebuild Services, Engine Rebuild Kits, Clutch Puller, Bearing Kits and more! His specialty is actually repairing/rebuilding 400 2-stroke engines, and people mail him complete engines from all over the USA.

On the 250 2-strokes that I own, the carbs are very easy to take apart and clean. We have 3x 250's, and I have had a 400 Scrambler in the past. One of the float needles leaked after converting the bike to premix, but no big deal.

I have taken all of the 2-stroke carbs apart and cleaned them when I first got the machine. Converted all the bikes to premix at 32:1 with polaris gold oil, and run stabil in the gas. Only use them 4-5 times a year; never had a problem with needing to rebuild the carbs. I've had the 2-strokes 4 years so far.

awesome articile. Thanks.. I have a 2005 500 Sportsman HO. Whats entailed in taking the carb off and cleaning it? Is it hard to get off the quad? I notice the 4x4/s are way harder to get to things as opposed to the sport quads. I had those my whole life but just got my first 4x4 this year.

Anti-sieze is what you use to keep screws from corroding,thus making them hard to get out resulting in stripped heads.

I replaced mine with little socket head screws of the same thread specs.

Have a problem with my 01 sportsman 500. It will start right up but after about 30 seconds at 1/4 to half throttle it will start to sputter and eventually die. But if you go to full throttle it will run fine. And after it dies it takes awhile for it to start running again. Has this happened to anyone or does someone know where to start lookong for a problem? Thanks

Have the valves every been adjusted?

Have never adjusted valves. I have taken the carb off and removed the bowl and everything looked clean. I sprayed carb cleaner in all the jets. None of that stuff helped.
