I have a polaris scrambler 400 4x4 fourwheeler that dies on me when i go over half throttle. It dies like it is out of gas and the fuel filter is dry like it ran out of gas. I pull the fuel line off and drain a little gas and it runs fine till it dose it again. I do have a bad shut off valve.(can run it all day withe fuel turnes off.) Would this be the problem i also checked the bowl float and it was fine. I getting real tired of this happing. Any help would be appricated.

Thanks,

Andrew

 

Check the gas tank vent line by loosenin the gas cap and see if it still does it.If it still does make sure the vent lines on the carb are in the correct location.Old Polaris Tech can get you right on this
