Ok- here’s a thought. I’ve run into similar situations on outboards. They run when the enrichment loop is active at startup and quit when it kicks out. Backfiring through intake can also be from lean mixture. Put a spark checker on and as the engine dies see if you continue to have spark as it winds down. Now it could also be timing, but if it runs rather normally at idle till it quits I would be less likely to think so. But for the heck of it check the crank position sensor. Good luck. Keep us posted.

      Anyone know anything about the Massimo Warrior 1000 MXD Crew UTV? I like the look but don't know anyone that owns one. All feedback is appreciated.

      I'm thinking of buying a snow blade for my Coleman Outfitter 550 (Hisun with Coleman stickers).
      Has anyone purchased a snow blade that can offer the make and model they bought and any comments, pros  cons etc.?
      Not 100% sure I'm going to buy, as the selection of blades for this model seems a bit thin on line. 
      Thoughts and comments welcomed.
      Thanks in advance.

      starts up you have keep rpms up for 5 minutes till it warms up then runs fine. But if it stalls wont start unless you unplug fuel pump and hold it to the floor till it starts then plug pump back in and run it till it warms up then it is fine all day.

      Unfortunately my rear Diff housing cracked on my 2013 and I need to replace it or find a good used complete differential.  I think the same one was used from 2013-2016?  Any help or referrals appreciated.  Thanks, Gary  (949)370-2575 (in UT)
