It sounds like it's going too lean..  Have you checked the fuel flow to the carb is adequate ? The best way is to turn the fuel tap off, then undo the carb drain screw and watch it flow out, then turn the fuel on and make sure it keeps flowing good. Then, with the engine warm, try adjusting the idle mixture. It should respond to a half turn either way, if it doesn't respond to a half turn in each direction(too lean and too rich), then there's a problem in the carb..

Another thing that might cause it would be tight valve clearances..  Unlikely if it has shim adjusters though.

Oh.. Tank breather too.. check that too, though that normally takes a while to manifest..

It does sound like it's running out of gas, but no spitting or sputtering it just dies. It sounds like it's idling at about 3000 rpm. I generally run mine carbs dry if I am not going to use it for a while and they don't sound like that, they slow down and then speed up before they die.

Good point Gw..  That is mostly the more common scenerio.. 

Thinking thinking...

I can't her that video.. bad internet..

So it's just running high steady revs is it, then suddenly cuts out ?

Carby breather hose blocked ?

      I rebuilt the carb on said machine. When I hook up the auxiliary gas tank it runs fine and everything is cool. When I put the fuel tank on and hooked up the lines, it completely flooded the cylinder and even about an inch of fuel in the air box. I'm pretty sure that it comes from the little hose on the petcock and hooks to the top of the carb. WTH is that even for? I mean the thing runs fine on the auxiliary tank, so idk And on the petcock when it's in the "on" position, I get no fuel. The petcock from the bike I took it apart and checked out how it operates. The sharpie marks indicate how it really works. Now the other petcock w/o the sharpie marks is an old one that was leaking that I removed from a Polaris quad. It's exactly the same thing, except the small hose and nipple have been removed. I'm so confused, LOL

      I'm working on a 2002 Polaris Sportsman 400 with shift indicator problems. The indicator panel only will show Neutral and Reverse. If it's in High or Low, the indicator will show "R".
      I have replaced the three position indicator switch on the transmission. There is also a two position switch on the tranny that I didn't replace. If anyone is familiar with this problem, please let me know what I need to do. Any help is greatly appreciated!

      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

      Hi All.  I introduced myself some weeks ago with my 2006 LT-F400F that needed a list of repairs including replacing the cracked generator cover.  It is back together as of last night and cranks up, idles and revs high pretty well.  Needs some fine tuning and stop backfiring at stop.
      The big issue is it will not go into gear.  I reassembled the insides with help from y’all’s posts.  The transfer selector moves from H-L-R, and the foot shifter moves thru the gears and finds neutral easily enough.  Before I tear it back open, the  transfer selector on top does not move as far as the repair manual says.  The diagram shows the shaft moving something like 40 degrees between L and H and 50+ degrees between L and R but it doesn’t move that far even though it finds the indent areas and moves well.  
      Could this be the problem.  I aligned all the dots on the shifter gears inside and it appeared to not be binding anywhere.  I do hear the gears touching when I shift like they are trying to engage, but zero movement from the ARV
      It was somewhat difficult to tell whether all the parts are installed on each shaft.
      Are there better/bigger photos somewhere that would allow me to be confident I included all the washers and bushings, etc?  If I had any doubt on parts that were laying inside after the cover broke then I purchased replacements from online stores.
      TIA for any input or feedback!!  Pics are from when I first took the generator cover off.
