over fuel

[DOAKLEY16]

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?

float level, crap on float needle jet. hold the throttle wide open when starting may help, attach tether ist.

-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.

what do you think would cause the gas gauge to allways say it is low?

Poor design. None of the ski-doo xp fuel gauges read properly.
