2009 summit x 800, the sled runs fine but when you shut it off it will get fuel into the carbs, then it wont start, iv had the shop looking at it for a week now and they cant find the problem? any answers?

-Make sure the fuel tank is not pressuring up by popping the cap.
-Check the vent hole in the LH bottom pan where the upper shock is mounted for blockage.
-Needle and seats could leaking
-There is a fuel shut off valve in the fuel pump untill you pull the engine over
-Make sure the heated carbs ar NOT on cause the engine will run rich and the the bottom end is loaded when you shut if off.
