hey guys. new hear. i just got a 95 big bear that ran fine when i looked at it, but now when i startit, it idles real bad. it runs for a bit at a higher idle, then dies right down and then dies. fire it back up and turn the idle screw in and it idles high. will run fine for a bit then stutters and idles down almost dies then lights up again, then a second later, dies. ive cleaned the carb the best i can . blew out the passages and tried again. still does the same . the air screw was bottomed right down. i opened it to about 2 turns out. seemed to bring the idle back up, then stuters and back down till almost dead, then dies. any suggestions?

      1998 Polaris Magnum 425 starts but dies right away.
      By BillR94
      I picked up this ATV that had no spark. The previous owner said he was driving it and it died and would not start. He discovered it had no spark. He replaced the CDI and the coil with no luck. He got tired of it and I bought it. I replaced the stater and now it has strong spark. Now, it starts for a second or two then dies. It will not stay running. I have checked the timing and it is spot on. The valves are adjusted correctly. I see no warn issues with the cam. I put the original CDI and coil back on it. Same problem exists. Compression is at 65 psi (has decompression mechanism),
      I took off the muffler in case the issue was clogged pipes. No change. I replaced the spark plug. No change. The carb was an aftermarket so I put a Niche carb on with no change. I bypassed the fuel pump and that did nothing to solve the problem. 
      I don't know if this is a carb issue or an ignition issue. I am looking around locally for an OEM carb to try out but not sure that will fix the problem. 
      Can anyone help me solve this problem. I am running out of ideas. 
      Thank you for your time
      Bill

      2007 Yamaha Grizzly 350 carb mixture screw
      By Louznmemind
      (Question is at the end if you want to skip my blabbering) I got this unbelievably well taken care of Grizzly 350 in for a carb clean, it belongs to an elderly couple that bought it brand new in '07. Apparently whoever has been doing their oil changes for them never checked the air filter..
      Obviously it got debris in the carb, it would still run but only idle with slight choke. I've taken it apart and cleaned it, have new o rings, gaskets, etc. As far as the mixture screw is concerned, I'm assuming I obviously need to remove the plug. I'm mainly a lawn equipment guy, I've worked on slide carbs in the past but never an unmolested one with the plug still intact. I hate to mess with it as the carb had very little debris but I'm sure the o ring needs to be replaced at minimum. Finally, the question: what's the best way of removing the plug? I DO NOT want to mess up this carb..

      Suzuki king quad 300 idles great but Boggs when you apply throttle
      By 97kingquad
      Okay so I bought this 1997 sazuki king quad from a guy and he had it for a few years. 
      He had it registered and on the trails last year but he said it bogged and backfired when he would try to drive it. so it sat for a year. 
      I bought it for 800 bucks and got it running that night and it ran great for a few days 
      But I parked it the other night and went to start it again and it was really hard to fire up and when I did it was bogging and idling high then low again.
      So I took the carb out and cleaned it (ended up doing it twice because it was still doing the same thing) 
      Now today I have it running slightly better, but it is still like 20% 
      I have been looking it up and trying to figure it out but I can't find the issue, has anyone else had this problem? I'll attach a video of it running and giving some throttle

      2003 Polaris Sportsman 400 - Right front tire will not disengage from AWD
      By wjmedic
      Recently rebuilt front end on this Polaris 400. New axles, bearings, seals, control arm bushings, Hilliard clutch thoroughly cleaned and inspected with no damage noted. 
      Everything put back to together. Placed bike on jack stands all four wheels off the ground, started in 2 WD switched to AWD both front tires spinning, when AWD turned
      off right front wheel will not disengage from AWD. Checked voltage at connectors both left and right connectors have no voltage with AWD switch off, and both have 12.4V
      when AWD switch is turned on. Repeated turning switch on and off several times with no change in condition. I am thinking this must be something mechanical with the 
      Hilliard clutch on the right hub ie. weak spring or stuck rollers on the Hilliard clutch assembly (Is this a logical thought?) any ideas on trouble shooting this before I disassemble the 
      right front hub again
