Hello my name is Josh and I'm new to this forum. I have a problem with my 03 Quadrunner 250 Idling way to high. I have rebuilt the carburetor and gave a proper cleaning. I have tried adjusting the idle screw but nothing happens. From what I can tell I don't have and vacuum leaks. When i spray carburetor cleaner on the air filter side it idles down to normal rpms and then after about a min or 2 it goes right back up. Any help will be appreciated im at my whits end with this. thank you

Check your intake boot for cracks. My buddy just went thru hell trying to fix an issue like that & it ended up being a bad boot. He rebuilt the carb, including choke curcuit, tried a new carb, then was looking @ timing before he found the bad boot! Lots of wasted time and money.

Thanks for the reply. I'll take a look again today when I get home. Yesterday I sprayed carb cleaner on the boots yesterday but it never change the idle until I sprayed directly into it.

      If anyone is having issues with the Mikuni VM24SS carb, I thought I would post what issues I had and how I resolved them.
      Acquired a 93 Bayou 220 that had sat for over 4 years.
      The carb was extremely corroded and pitted and full of leftover fuel.
      Cleaned carb and bowl and was able to get the engine to start.
      Within 30 seconds exhaust would heat up and start to glow red hot.
      Removed carb and recleaned everything, including a second overnight soak.
      Needless to say, after removing the carb for the 5th time and my frustration to the limit I
      realized that my attention had been to the carb body and not to the bowl.
      There is a small brass rod on the bottom of the carb that goes down into the float bowl but is seperated from the main section. I had cleaned that area very well....I had thought.
      ***The corrosion had sealed off the channel that runs from the main bowl section to the small tube section on the side of the float bowl. No amount of carb cleaner was going to get it to budge. So i took a small nail and started to scrape away the corrosion and was eventually able to dislodge enought of the corrosion that carb cleaner would flow through that channel. ***
      I thoroughly cleaned each side of the channel in the float bowl and reinstalled the carb and now the issue of it running lean is gone.
      On a second note the fuel mixture screw was a nightmare to remove as the threads had been corroded and wouldnt let the screw come out. I used a little cutting oil and worked the mixture screw in and out until I was able to push past the corroded threads and completely remove the needle. After a couple passes with a tap to clean the threads it is like new again.
      Hope this helps if you are having a lean running machine.

      Hello all! I’m new to the 4 wheeler world, but not new to the mechanic world. I was a diesel mechanic for many years and last year got into jet skis. I just bought a 1987 Yamaha moto 4 350 and now learning the ins and outs of 2 stroke engines. Looking forward to learning all the things.

      I bought a 1996 Sportsman 500 4x4 about a month ago, and I love it. Unfortunately, I've been experiencing a few problems with the high-range gear. The first problem is that the gear selector will intermittently pop out of high and into neutral. This problem will sometimes occur when starting from a stop and sometimes will also occur while at cruising speed. The last time this happened I stopped and put it back into gear, however, as soon as I tried to throttle the machine would die. I turned it on again with no problems put it back into high and it died again. Once again I turned it on with no problems put it into low instead and it worked fine with no problem. I drove in low down the road slowly for a little and then shifted back into high with no issues. 
         I plan on working on it this weekend and would just like some opinions or feedback from anyone who may have experienced these problems before. I'm very mechanically inclined but im unsure of exactly where to start as this is the first Polaris ATV that I've owned. Any feedback is appreciated and thanks in advance
