2014 Honda Rancher TRX420TM1: Starts but once it warms up it stalls

2014 Honda Rancher TRX420TM1: Unit starts right up, once it warms up it stalls and more difficult to start but once it does start it won't stay running. I have replaced the fuel assembly, IACV, O2 sensor and fuel injector. There are no active DTC codes. Disconnecting fuel line at injector and turning on key there is a steady stream of fuel. Plug looks good did not see crack in ceramic. Is there any way to test the ignition coil?

Thanks for any help.

      Hi, I am having issues with my TRX350D fuel pump.  It suddenly stopped running so I have replaced all the fuses and cleaned all the terminals.  I have fitted a new pump, fuel cut-off relay and rectifier.  Still nothing!!  The pump runs when attached to a battery.  The engine will start on the choke and the filter fills with fuel but it will  not rev and dies when the choke is closed. I have power to the relay but nothing at the pump black/white wire when cranking the engine.  Any ideas where to go from here would be very much appreciated!!

      Hi everyone. 
      Let me explain the thread title. 
      My husband and I are very active in the nudist community, and we have stayed at many and most of the mainstream nudist and clothing optional campgrounds in the USA. We are now approaching our retirement and would like to start a podcast to share those off the road / backwoods / little known camping areas where nudity is allowed. We have purchased a 5th wheel camping trailer with a rear garage for the ATV and now need some good reports on the one to buy. 
      We are most interested in a side by side unit but would love to get your thoughts. 
      Feel free to stop by and say Hi and ask anything you would like to better understand what we are looking for in an offroad unit. 
      Thanks for reading and hope to hear from you.

      This is something I'm extremely curious about. Has anyone ever attempted to buy a quad (or any other vehicle) from an impound lot? I've always wondered if this could be a bargain, or a waste of time. Google searches do turn up some helpful results. Looks like the state of NJ holds auctions online which I'd be a bit hesitant about.
       
      My online searches haven't really turned up any results of anyone buying an ATV this way. I'd be really curious if anyone tried this, or knows someone who has. I've actually found a couple pages with online auctions for my state, but none had ATVs.

      I am working on a basket case for a friend.  It is a 98 Big Bear (YFM350FWB).  It came with a parts machine which is a 96, which I am coming to find out is VERY different from his machine.
       
      Anyway, first thing is first.  I checked compression, 150psi.  Valves are set correctly, and the engine is in time.  I cleaned the carb, and there was some junk in the passages.  It is a chinese carb, which I figured from the lack of markings or lettering altogether.
       
      The bike runs.  It idles ok, but breaks up badly under acceleration.  Pulling a new spark plug shows it is running lean.  White strap, with no black whatsoever.  So I have the carb adjusted with the mixture screw out way too much (about 5 turns), and the diaphragm needle lifted to the top slot.  It is still not getting enough fuel (or too much air).  It backfires through the carb, and cannot get above idle without carrying on.  The carb boot is in good shape, so it isn't pulling any air there.  I did test this as well by spraying ether around the boot when running, looking for intake leaks.
       
      Anything big I am missing here?  I am starting to believe that this chinese carb is the issue.  This quad came with the original carb, which I would like to rebuild and use, but the mixture screw is totally stuck, and stripped way down in its recess.  
       
      Thanks for any assistance.
