I've Change oil filters, plug seems fine no carbon fowling of any kind, cleaned tank, carb....... HELP!!!! PLEASE!!!! (lol) Any sugesstions is greatly appreciated. Thank You,
Paul (cerable)

 

huh dont sound like fun riding!!!!! sounds to me like carb all the way. needle valve maybe. if the carb has been cleaned properly i dont think it would hve to do with jetting. unless you are ridding in a big elevation change. also you may have choke trouble, does smell like it is running rich when it does run. maybe you chokin out. well good luck sorry i didnt have a real answer for you. if you cant get it the 700 kq starts every time first time and they run great maybe try that route.[img]i/expressions/face-icon-small-smile.gif[/img]

 

Make sure the pitcock on the fuel tank is not plugged and all a the line are in good shape
